This study was conducted to investigate one of the most issues in Iraqi Awassi sheep by ingesting of Tribulus terrestris that disseminated in the Al-Najaf Desert. The Iraqi Awassi sheep is one of the most popular and economically important sheep in Iraq and the Middle East which survive on the low nutrition level. Nutrition also remains one of the major constraints to livestock production in the tropics, particularly the lack of protein during the dry season. Tribulus terrestris (Qutub) belongs to family Zygophyllaceae, it is a herbaceous, mat forming plant in nature and grows in warm dry tropics all over the world. A total of 75 blood samples were collected from jugular vein and placed into EDTA and plain tubes. Samples were divided in to two groups depending on the clinical signs, 45 sheep were clinically healthy and 30 sheep possessed clinical signs that are suggestive of photosensitization in Al-Najaf governorate, Iraq. The results showed that the total blood analyses, there were a significant increase (P > 0.05) in total leukocyte count and neutrophils, while, there was no significant difference in total red blood cells, PCV, Hb, lymphocytes, and eosinophil of affected sheep compared to the control. Furthermore, affected sheep had significantly higher levels of aspartate aminotransferase (AST), alkaline phosphatase (ALP), sorbitol dehydrogenase (SDH), total protein, total bilirubin, and serum urea nitrogen. In conclusion, the present study recorded that hematological, biochemical and pathological changes related with ingestion of toxic plant Tribulus terrestris in Al Najaf desert of Iraq, which causes photosensitization in affected sheep.

Recommendations of products with Tribulus terrestris as anabolic enhancers are based on empirical data. Exposure, especially of athletes, is very high, being among the most widely used nutritional supplements. Consumption of products containing Tribulus terrestris extracts has increased rapidly in the past few years due to the high content of sterol saponosides, compounds with presumed anabolic properties. Because of this upward surge, their efficacy and/or their safety are more and more often questioned. Commercialized dietary supplements, are often mislabelled, adulterated, or contaminated, therefore an evaluation of benefit/risk balance should always be conducted. Our study aimed to analyse an herbal drug and a food supplement frequently encountered on the market. Total polyphenolic and total saponosides content were determined. Inductively coupled plasma atomic emission spectrometry (ICP-AES) was used to determine mineral element content of Tribulus terrestris products. Antioxidant and antimicrobial activities were assayed. The extract obtained with the herbal drug had no antibacterial effect. The extract from the capsules, however, was active against all tested strains with higher activity against Methicillin-resistant Staphylococcus aureus and Escherichia coli (MIC = 0.78 mg/mL). Trace elements were quantified, and dose-related risks were outlined, raising awareness regarding the aluminum and nickel content in the herbal drug.

The proprietary DA-5512 formulation comprises six herbal extracts from traditional oriental plants historically associated with therapeutic and other applications related to hair. Here, we investigated the effects of DA-5512 on the proliferation of human dermal papilla cells (hDPCs) in vitro and on hair growth in C57BL/6 mice and conducted a clinical study to evaluate the efficacy and safety of DA-5512. DA-5512 significantly enhanced the viability of hDPCs in a dose-dependent manner ( p<0.05 ), and 100 ppm of DA-5512 and 1 μ M minoxidil (MXD) significantly increased the number of Ki-67-positive cells, compared with the control group ( p<0.05 ). MXD (3%) and DA-5512 (1%, 5%) significantly stimulated hair growth and increased the number and length of hair follicles (HFs) versus the controls (each p<0.05 ). The groups treated with DA-5512 exhibited hair growth comparable to that induced by MXD. In clinical study, we detected a statistically significant increase in the efficacy of DA-5512 after 16 weeks compared with the groups treated with placebo or 3% MXD ( p<0.05 ). In conclusion, DA-5512 might promote hair growth and enhance hair health and can therefore be considered an effective option for treating hair loss.

Objective: The primary objectives were to compare the efficacy of extracts of the plant Tribulus terrestris (TT; marketed as Tribestan), in comparison with placebo, for the treatment of men with erectile dysfunction (ED) and with or without hypoactive sexual desire disorder (HSDD), as well as to monitor the safety profile of the drug. The secondary objective was to evaluate the level of lipids in blood during treatment. Participants and design: Phase IV, prospective, randomized, double-blind, placebo-controlled clinical trial in parallel groups. This study included 180 males aged between 18 and 65 years with mild or moderate ED and with or without HSDD: 90 were randomized to TT and 90 to placebo. Patients with ED and hypertension, diabetes mellitus, and metabolic syndrome were included in the study. In the trial, an herbal medicine intervention of Bulgarian origin was used (Tribestan(®), Sopharma AD). Each Tribestan film-coated tablet contains the active substance Tribulus terrestris, herba extractum siccum (35-45:1) 250mg which is standardized to furostanol saponins (not less than 112.5mg). Each patient received orally 3×2 film-coated tablets daily after meals, during the 12-week treatment period. At the end of each month, participants' sexual function, including ED, was assessed by International Index of Erectile Function (IIEF) Questionnaire and Global Efficacy Question (GEQ). Several biochemical parameters were also determined. The primary outcome measure was the change in IIEF score after 12 weeks of treatment. Complete randomization (random sorting using maximum allowable% deviation) with an equal number of patients in each sequence was used. This randomization algorithm has the restriction that unequal treatment allocation is not allowed; that is, all groups must have the same target sample size. Patients, investigational staff, and data collectors were blinded to treatment. All outcome assessors were also blinded to group allocation. Results: 86 patients in each group completed the study. The IIEF score improved significantly in the TT group compared with the placebo group (Р<0.0001). For intention-to-treat (ITT) there was a statistically significant difference in change from baseline of IIEF scores. The difference between TT and placebo was 2.70 (95% CI 1.40, 4.01) for the ITT population. A statistically significant difference between TT and placebo was found for Intercourse Satisfaction (p=0.0005), Orgasmic Function (p=0.0325), Sexual Desire (p=0.0038), Overall Satisfaction (p=0.0028) as well as in GEQ responses (p<0.0001), in favour of TT. There were no differences in the incidence of adverse events (AEs) between the two groups and the therapy was well tolerated. There were no drug-related serious AEs. Following the 12-week treatment period, significant improvement in sexual function was observed with TT compared with placebo in men with mild to moderate ED. TT was generally well tolerated for the treatment of ED.

Along with the apparel or clothing industry, diversified uses of natural lignocellulosic fibre are getting popularity in many fields e.g., composites, automotive, marines, aerospace, electronics, civil construction, nanotechnology, biomedical, etc. The property and uses of textiles are determined by their constituent fibre properties. The proximate composition and thermogravimetric analysis (TGA) data of a total of 9 local hemp and flax genotypes (3 and 6, respectively) were carried out to understand their suitability in different applications. A wide variation was observed in the ash content of hemp and flax fibres varied from 1.7 to 17.7%, crude protein 3.27 to 9.02%, crude fibre 26.51 to 55.32%, ether extract 2.6 to 20.9% and energy value 284.44 to 383.96 kcal 100-1 g. In TGA analysis, all the fibres showed a similar trend. The flax genotypes contain lower ash and ether extract and higher DM, crude carbohydrate and crude fibre than hemp genotypes. Therefore, flax could be used in the lightweight composite, textile, pulp and cellulose-based industries. The hemp fibre had higher ash which was reflected by a higher residue at 500 o C in TGA analysis. To understand the viability of these flax fibres, further investigations are needed.

Cancer is the third leading cause of premature death in sub-Saharan Africa. Cervical cancer has the highest number of incidences in sub-Saharan Africa due to high HIV prevalence (70% of global cases) in African countries which is linked to increasing the risk of developing cervical cancer, and the continuous high risk of being infected with Human papillomavirus In 2020, the risk of dying from cancer amongst women was higher in Eastern Africa (11%) than it was in Northern America (7.4%). Plants continue to provide unlimited pharmacological bioactive compounds that are used to manage various illnesses, including cancer. By reviewing the literature, we provide an inventory of African plants with reported anticancer activity and evidence supporting their use in cancer management. In this review, we report 23 plants that have been used for cancer management in Africa, where the anticancer extracts are usually prepared from barks, fruits, leaves, roots, and stems of these plants. Extensive information is reported about the bioactive compounds present in these plants as well as their potential activities against various forms of cancer. However, information on the anticancer properties of other African medicinal plants is insufficient. Therefore, there is a need to isolate and evaluate the anticancer potential of bioactive compounds from other African medicinal plants. Further studies on these plants will allow the elucidation of their anticancer mechanisms of action and allow the identification of phytochemicals that are responsible for their anticancer properties. Overall, this review provides consolidated and extensive information not only on diverse medicinal plants of Africa but on the different types of cancer that these plants are used to manage and the diverse mechanisms and pathways that are involved during cancer alleviation.

Tribulus terrestris have been traditionally used as folk medicine owing to its rich source of polyphenolic compounds. The aim of the present study was to assess the antioxidant potential by performing quantification of polyphenolic compounds present in Tribulus terrestris fruit through HPLC analysis. Various extracts of Tribulus terrestris fruit were prepared through microwave-assisted extraction (MAE) carried out at three different time intervals of 1, 3, and 5 minutes respectively. The extracts were then subjected to antioxidant characterization. The results showed maximum values of TPC, TFC, DPPH, FRAP, and ABTS assay for the extract prepared at 3 minutes as 54.86±0.51mg GA/g, 544.33±4.50mg QE/g, 87.67±0.57%, 1051.67±3.21mM Fe+2/g, and 86.34±2.08% respectively. However, the minimum values of TPC, TFC, DPPH, FRAP, and ABTS were observed for the extract prepared at 1 minute heating time as 39.27±0.36mg GA/g, 282.66±3.51mg QE/g, 60.33±1.15%, 756.34±4.50mM Fe+2/g, and 66.33±1.52% respectively. Quantification of major polyphenolic compounds in microwave-assisted Tribulus Terrestris fruit extract was performed through HPLC analysis. The results of the analysis detected twenty-four polyphenolic compounds. The maximum concentration was detected for naringin i.e., 4694.18 mg/100g of dried extract among flavonoids, while the maximum phenolic acid was found to be salicylic acid i.e., 728.41 mg/100g of dried extract.

ETHNO-PHYTOTECHNOLOGY combines ethnobotany and biotechnology. This study evaluated the ethnobotanical role, anticancer potential, and allelopathy of Tribulus terrestris L. The ethnobotanical survey of twenty informants used an open-ended questionnaire. T. terrestris contains steroids, saponins, antioxidants, flavonoids, alkaloids, phenolics, proteins, and amino acids. The study investigated cytotoxic effects using six carcinoma cell lines. Hordeum vulgare and Lepidium sativum were used as recipient species in the allelopathy experiments. We found that 95% of the informants stated that T. terrestris is an aggressive species that injures livestock, reduces biodiversity, leads to soil dryness, consumes large amounts of space during the vegetative season, and affects soil pH and the absorption of minerals. Ethanolic extracts produced a significant effect on the prostate (PC3), breast (MCF 7), lung (A549), and liver (HEP-G2) carcinoma cell lines, with IC50 values of 19, 22, 33, and 33μg/mL, respectively. The intestinal carcinoma cell line (CAco2) had an IC50 60μg/mL. The colon (HCT) carcinoma cell line had an IC50 value of 68 μg/mL. Water extracts inhibited the seed germination, plumule length, radicle growth, and fresh and dry matter production of the recipient species. This study demonstrated that T. terrestris is potentially valuable as an anticancer agent and an herbicide against harmful weeds.

For a long time, many cultures around the world have used Tribulus terrestris L. in the prevention and treatment of various diseases. In this study, the antioxidant activity and total phenolic and flavonoid content of extracts obtained with various solvents from T. terrestris plant collected from different localities in Kahramanmaraş were investigated. In addition, the fixed oil content of the extracts was examined by GC-MS analysis and as a result, 26 different fatty acids were determined. The main fatty acid components of plant extracts are linoleic acid, oleic acid and palmitic acid. The total phenolic substance value of plant extracts varies between 2.20-18-77 mg g-1, total flavonoid amount varies between 0.06-0.50 mg g-1, FRAP value varies between 6.16-23.50 µg g-1 and DPPH value varies between 1.54-10.54 µg mL-1. It was observed that the solvents used in extraction affected the bioactivity values rather than the locations. Although the absorbance values of the extracts obtained with hexane were high, low extract yield affected the results. The highest values in all characters examined were obtained from ethanolic extracts.

Background/objectives: Steroidal saponins are widely distributed in medicinal plants with potential applications in cardiovascular disorders. Gitogenin, a saponin, has not been explored as antihypertensive; this investigation was aimed to explore its blood pressure lowering potential and underlying mechanisms. Methodology: The effect of gitogenin was evaluated on blood pressure in vivo, using normotensive rat model and the underlying cardiovascular mechanism(s) in vitro, in isolated rat aorta and in atria preparations using PowerLab data acquisition system (ADInstrument, Australia). Results: Intravenous injection of gitogenin decreased mean arterial pressure (MAP) in anesthetized rats. Atropine (1 mg/kg) and L-NAME (100 mg/kg) pretreatment significantly (*p < .05) attenuated effect on MAP to gitogenin. In isolated intact aortic rings, gitogenin induced endothelium-dependent vasodilatation (maximum 65%), which was ablated (maximum 22%) with L-NAME (100 mg/kg) and atropine (1 μM) pretreatment or endothelium removal. Gitogenin was found more potent against angiotensin II precontractions without effect on high K⁺ and low K⁺ precontractions. In isolated rat right atria, gitogenin suppressed rate and force of contractions. Atropine (1 μM) pretreatment partially inhibited effect of gitogenin on force and eliminated its effect on rate. Combined atropine (10 μM) and atenolol (0.5 μM) pretreatment was without effect on force of contractions but eliminated effect of gitogenin on rate with 25% increase. Conclusion: These findings indicate that antihypertensive effect of gitogenin is the outcome of vascular and cardiac effects; agonistic effect on vascular M3 and cardiac M2 receptors; and being more selective for M2. Increase in the rate of atrial contraction might be of clinical importance.

The present research work is based on the identification of Invasive Alien Plant Species (IAPS) distributed in Potohar Plateau, which are threat to indigenous flora. To confirm the invasive and alien status of these species, we investigated the flora of Potohar plateau. The target population sampling method was used for the collection and listing of IAPS present in all districts of Potohar Region. Invasion status of IAPS was recorded from wastelands, roadsides, crop fields, banks of canals, mismanaged gardens and housing colonies. Our results revealed that Broussonetia papyrifera Vent., Cannabis sativa L., Eucalyptus camaldulensis Dehnh., Lantana camara L., and Parthenium hysterophorus L. are highly invasive species. Whereas seventeen IAPS were found in naturalized, ten recently escaped from controlled cultivation, three were newly introduced while fifteen grown casually in the study area. The common life form of IAPS was herbs and are used for medicinal and ornamental purposes. These species have invaded maximum area to obstruct the distribution of native flora including medicinal and economically important plants, which are now found in patches. We tend to use eradication methods to control further replacement of indigenous vegetation. This study suggests that the Government of Pakistan should take possible steps to prevent natural habitat of local flora and make separate zones for IAPS. The present study will help the researchers and policymakers to control invasion and alien species.

Khella (Ammi visnagais) was used in Ancient Egypt as a herbal remedy for renal colic. Khella contains group of coumarins, xanthotoxin, ammidin, furoquinoline alkaloids and, dihydroseselins with varying cytotoxic activity. The most common is Khellin and visnagin. Khellin was found to be a smooth muscle relaxant, induces diuresis, increases excretion of citrate and decreases the excretion of oxalate in urine, which improves nephrolithiasis and passage of ureteric stones. Synthetic derivatives of khellin include amiodarone, the anti-arrhythmic drug, and cromolyn, an anti-asthma drug. Khellin is not as safe as it seems to be. Its oral use is limited by its potential toxicity (eg, elevated liver enzymes, phototoxicity, dermatitis). In experimental animals, the median lethal dose (LD50) was 3.6 g/kg for intra-peritoneal administration and 10.1 g/kg for oral administration. In humans, nausea and vomiting were observed frequently in 29% and transaminitis in 7-14% of the patients. Other potential adverse reactions include dizziness, constipation, headache, itching, insomnia, photosensitivity and lack of appetite. We report for the first-time, acute kidney injury following use of khella in a CKD patient with a 5-fold increase in his serum creatinine level from 1.9 to 9.2 mg/dl. His renal biopsy revealed eosinophilic interstitial nephritis. He responded well to pulse methylprednisolone followed by short course of oral steroids. We believe this is the first case describing Khella nephropathy. Herbal nephropathy is not uncommon and herbal remedies are not as safe as it is believed. Accurate diagnosis and early management are the key in improving the renal outcome.

The general spread of Tribulus terrestris L. (South Africa, Australia, Europe, and India), the high content of active ingredients (in particular sterol saponins, as well as flavonoids, tannins, terpenoids, phenol carboxylic acids, and alkaloids), and its frequent uses in folk medicine, and as food supplements highlight the importance of evaluating its phytopharmacological properties. There are miscellaneous hypotheses that the species could have a high potential for the prevention and improvement of various human conditions such as infertility, low sexual desire, diabetes, and inflammatory diseases. Worldwide, numerous herbal supplements are commercialized with indications mostly to improve libido, sexual performance in both sexes, and athletic performance. Phytochemical studies have shown great disparities in the content of active substances (in particular the concentration of furostanol and spirostanol saponoside, considered to be the predominant active ingredients related to the therapeutic action). Thus, studies of experimental pharmacology (in vitro studies and animal models in vivo) and clinical pharmacology (efficacy and safety clinical trials) have sometimes led to divergent results; moreover, the presumed pharmacodynamic mechanisms have yet to be confirmed by molecular biology studies. Given the differences observed in the composition, the plant organ used to obtain the extract, the need for selective extraction methods which are targeted at the class of phytocompounds, and the standardization of T. terrestris extracts is an absolute necessity. This review aims to highlight the phytochemical, pharmacological, and toxicological properties of T. terrestris, with a focus on the contradictory results obtained by the studies conducted worldwide.

Erectile dysfunction (ED) or male impotence is described as an inability to maintain penile erection primarily endothelial and neuronal dysfunction which is partly characterized by decreased production of nitric oxide (NO). Male impotence can be caused by androgen deficiency in aging men, atherosclerosis, diabetes mellitus, spinal cord injury, high level of cholesterol, hypertension, prostate surgery, prostate and heart disease, penis anatomical deformity, social and psychological conditions as unhappy marital relationship, depression, and stress. Aphrodisiac is a drink or food that arouse sexuality. It can be categorized into three groups according to their action mode as follows: increase sexual pleasure substances, increase libido substances (arousal, sexual desire), and increase sexual potency (erection effectiveness). Various extracts of medicinal plants and orally active drugs such as vardenafil, sildenafil, and tadalafil are used to increase arterial blood flow for treating (ED) in southwest Asia. Hence, this paper review focuses on medicinal plants used as aphrodisiacs for scientific validation and management of erectile dysfunction (ED).

This review article is an effort to summarize the medicinal plant status, history, research, prospects and limitation in Pakistan. Therapeutic plants are the important part of the healthcare system. Over 400.000 higher plants species are identified so far; of which about 10% are utilized by different communities for medicinal purposes. In Pakistan, the majority of the people depend on therapeutic plants for curing minor ailments and in certain circumstances major ailments too. All over the world, there various treatment systems exist like Ayurvedic, Allopathic medicine, Chinese treatment system and Homeopathic medicine. China and Indo-Pakistan are at the center of the international herbal market. According to an estimate, the global trade of herbal drugs values 25-30 billion US$ per annum. Because of over-collection many medicinal plants are near extinction. Native plant gatherers and sellers are the main cause of threat to the Pakistan medicinal flora. Although the medicinal flora is the income source for indigenous people, this resource is not managed properly, which may result in habitat destruction, as well as species extinction. It is high time to find sustainable ways for harvesting medicinal plants from the wild, to educate native collectors in suitable collection methods, to train the local community how to grow therapeutic herbs, and to eliminate the middle-men from the trading chain.

Background and Objectives Mudabbar/Tadbeere advia is referred to the processes performed on the drugs to detoxify, purify, and enhance therapeutic action and to reduce its doses before making the formulations in Unani medicine. It improves quality of drugs either by optimizing its desirable characteristics or minimizing the undesirable ones; it makes drug effective, safe, and specific. There is a need of comparative evaluation to understand its significance. Tadbeer of Kharekhasak (KK) khurd (Tribulus terrestris Linn. fruit) is described by Rabban Al-Tabari in Firdausul Hikmat, Akbar Arzani in Qarabadeene Qadri, etc., during the compounding of aphrodisiac formulations. Mudabbar Kharekhasak (MKK) used in Safoofe Kharekhasak mentioned in Al-Qarabadeene was evaluated in this work. Methods Mudabbar/Tadbeer process was carried out by blending fresh KK. Juice with powdered dry KK and drying it under the sun. Juice used for process is thrice the weight of dry KK powder. The KK before and after the process was evaluated using physicochemical tests: powder characterization, extractive value, alcohol and water soluble matter, ash value, loss on drying (LOD) at 105°C, pH, high-performance thin layer chromatography (HPTLC) fingerprinting, and diosgenin content. Results Powder characterizations were set in. Increase in successive and nonsuccessive extractive values in various solvents, water/alcohol-soluble content, total ash, acid-insoluble ash, water-soluble ash, and sulfated ash of MKK was noted in comparison with KK. Decrease in LOD at 105°C and pH of MKK powder was observed. HPTLC fingerprinting data were developed for the identification and evaluation. Quantification of diosgenin content increased to 432.1 g/g in MKK as compared to 144.5 g/g in KK, suggesting significant increase in saponin content. Conclusion Data obtained clearly indicated changes in MKK validating the classical Mudabbar process, probably to enhance/modify the action of drug. Standards for crude and MKK were established for future reference. SUMMARY Mudabbar process on Tribulus terrestris Linn (KK) have been validated.

In the Mediterranean Basin, petroleum energy resources are scarce. For an environmentally sustainable solution, the seeds collected from wild plants indigenous to this area could be used as biodiesel producers to meet the energy demand. For this, the fatty acid profiles of seed oils from 127 species belonging to 30 plant families, all native of the Mediterranean Basin, were surveyed in a search for fossil-fuel substitutes. The saponification number (SN, mg KOH/g), iodine value (IV, g I2/100 g), cetane number (Ф), higher heating value (δ, MJ/kg), cold filter-plugging point (CFPP, ºC), density (ρ, g/cm³), induction period (IP, h) and kinematic viscosity (η, mm²/s) were empirically determined and then used to establish the suitability of the different seed oils for biodiesel production. The aptness to serve as biodiesel was determined by applying the specification for biodiesel standard made by several organizations. In addition to three already well-characterized species, the fatty acid methyl esters from the seeds of Conium maculatum (Ф= 53.7; δ= 40.1), Eryngium maritimum (Ф= 53.2; δ= 40.2), Nigella damascena (Ф= 58.1; δ= 40.1), Portulaca oleracea (Ф= 62.9; δ= 40.5), Prangos uechtritzii (Ф= 52.8; δ= 40.1), and Tribulus terrestris (Ф= 59.4; δ= 40.1), meet the major quality standards set by several organizations, and thus are suitable for biodiesel production. Data from empirical models used for estimating biodiesel properties was compared with experimental data from biodiesel prepared with available seeds, and good correlations between the two methodologies were found.

The present study examined the potential capacity of cement dust pollution on human health at Gharbanyyate district. The objective was prolonged to endorse specific herbal formulas (suggested solution) as supplements for decreasing the noxious consequences of the frequent heavy metals on human. Soil samples were collected from topsoil (0-30 cm) at various distance points around the cement factory and analyzed for some specific heavy metals. Control samples were taken opposite the wind direction 3200 m from the factory. This paper recognized certain divergent means by which these metals can be presented in the human body. An herbal assemblage (ABCOSTU; Arctium lappa, Berberis vulgaris, Coriandrum sativum, Olea europaea, Silybum marianum, Tribulus terrestris and Urtica dioica) was prepared in according to the kinds and categories of the different heavy metals concentrations. It was proved that soil pH fluctuated between 6.18 to 8.43 versus the controlled pH with value 6.11. The EC level as well as Cr and Cd significantly (p≤ 0.05) decreased with increasing distances from the factory. Assemblage of six continues months was applied and demonstrated a significant enhancement (p≤ 0.05) in the medical examined cases documented in the study areas. The study suggests a potential association between exposure to cement dust and an increased risk of some diseases including respiratory diseases as well stomach and rectal cancers. Instituting healthcare specialized sequences in these polluted areas are essential as an important portion in the plan of the sustainable development plan in order to rescue the affected rural communities.

Ethnopharmacological relevance: Fructus Tribuli (FT), a traditional Chinese medicinal herbal, has been used for the clinical treatment of cardiovascular diseases for many years and affects vascular endothelial dysfunction (ED) in patients with hypertension. Aim of the study: This study aimed to demonstrate the pharmacodynamic basis and mechanisms of FT for the treatment of ED. Materials and methods: The present study used ultra-high-performance liquid chromatography coupled with quadruple-time-of-flight mass spectrometry (UHPLC-Q-TOF/MS) to analyze and identify the chemical components of FT. The active components in blood were determined after the oral administration of FT by comparative analysis to blank plasma. Then, based on the active components in vivo, network pharmacology was performed to predict the potential targets of FT in treating ED. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were also performed, and component-target-pathway networks were constructed. Interactions between the major active components and main targets were verified by molecular docking. Moreover, spontaneously hypertensive rats (SHRs) were divided into the normal, model, valsartan, low-dose FT, medium-dose FT, and high-dose FT experimental groups. In pharmacodynamic verification studies, treatment effects on blood pressure, serum markers (nitric oxide [NO], endothelin-1 [ET-1,], and angiotensin Ⅱ [Ang Ⅱ)]) of ED, and endothelial morphology of the thoracic aorta were evaluated and compared between groups. Finally, the PI3K/AKT/eNOS pathway was analyzed by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot of the thoracic aorta of rats in each group to detect the mRNA expression of PI3K, AKT, and eNOS and the protein expression of PI3K, AKT, p-AKT, eNOS, and p-eNOS. Results: A total of 51 chemical components were identified in FT, and 49 active components were identified in rat plasma. Thirteen major active components, 22 main targets, and the PI3K/AKT signaling pathway were screened by network pharmacology. The animal experiment results showed that FT reduced systolic blood pressure and ET-1 and Ang Ⅱ levels and increased NO levels in SHRs to varying degrees. The therapeutic effects were positively correlated with the oral dose of FT. Hematoxylin-eosin (HE) staining confirmed that FT could alleviate the pathological damage of the vascular endothelium. qRT-PCR and Western blot analysis confirmed that up-regulated expression of the PI3K/AKT/eNOS signaling pathway could improve ED. Conclusions: In this study, the material basis of FT was comprehensively identified, and the protective effect on ED was confirmed. FT had a treatment effect on ED through multi-component, multi-target, and multi-pathways. It also played a role by up-regulating the PI3K/AKT/eNOS signaling pathway.

The present study aimed to produce a novel biocompatible, stable and biodegradable exopolysaccharide (EPS) from endophytic bacteria to deliver drugs into malignant cells effectively. EPS-producing endophytic bacteria, Pseudomonas otitidis was isolated and identified from the roots of the medicinal plant Tribulus terrestris L. The ice-cold ethanol precipitation method was used to isolate EPS from an endophytic bacterial culture. The isolated EPS was partially characterized by Fourier transform infrared spectroscopy (FTIR), Nuclear magnetic resonance (NMR) spectroscopy, and the presence of reducing sugar and protein contents were also measured. The isolated EPS contained 26.665 ± 1.302% of reducing sugar and 0.912 ± 0.023% of proteins. Further, EPS-based quercetin-loaded nanoparticles (NPs) were formulated through the precipitation method to deliver quercetin into breast cancer cells. The fabricated nanoparticles size, shape, physical nature, drug release and release kinetics properties were studied and confirmed. EPS-based nanoparticles could cause the highest release of quercetin in an acidic medium at pH 5.0, and they had high biocompatibility in a physiological medium. In addition, the NPs showed significant free radicals (DPPH* and ABTS*) scavenging and ferric ion reducing potentials and concentration-dependent cytotoxic effects against breast cancer cell lines (MCF-7 cells) after 24 h treatment with IC50 value of 14.313 μg/mL. The obtained results demonstrated that the isolated EPS from endophytic bacteria can positively applied as a drug delivery vehicle and enhanced the activity of the loaded drug.

The purpose of this study was to illustrate the mechanism of “enzyme inactivation and toxicity reduction” of Fructus Tribuli (FT) after being heating processed. Ultra-high performance liquid chromatography coupled with triple quadrupole tandem mass spectrometry (UHPLC-MS/MS) was used to quantitatively analyze the contents of four steroidal saponins in crude Fructus Tribuli (CFT) and stir-fried Fructus Tribuli (SFT) under different storage times at room temperature. The enzyme activity of β-D-glucosidase in CFT and SFT were determined and calculated by ultraviolet–visible spectrometry (UV-VIS spectrometry). In addition, the enzyme hydrolysates of FOT and tribuluside A were qualitatively analyzed by ultra-high-performance liquid chromatography coupled with quadruple-time-of-flight mass spectrometry (UHPLC-Q-TOF/MS). The hepatorenal toxicity of spirostanol saponins in FT were further confirmed by in vivo and in vitro experiment. This study confirmed that “enzyme inactivation and toxicity reduction” was one of the reasons why the stir-frying can reduce hepatorenal toxicity of FT, and further enriched the exploration on the mechanism of processing toxicity reduction.

ABSTRACT: Herb in botanical sense is a plant lacking a permanent woody stem that produces seeds and flowers that dies after its growing season. In traditional medicine sense herb is small, non woody plant valued for its medicinal, savory or aromatic compounds. It is estimated that about 25% of all modern medicines are directly or indirectly from higher plants and according to World Health Organization, 80% of the people worldwide rely on herbal medicine. However, usage of traditional remedies increases when conventional medicine is ineffective in the treatment of disease, such as in advanced cancer and in the face of new infectious diseases. Villagers chiefly depend on the herbs for all diseases. Herbs are natural or having no or low probability of side effects. These are holistic and oldest and most widely used form of medicine. Herbs are used from ancient time and now are popular among people of both urban and rural areas for cure of different ailments. Herbal medicine offers safe, gentle and effective treatment. It does not just treat the isolated signs and symptoms of disease but treats the whole of us – physically, mentally and emotionally because the healing cannot be fully achieved unless all three are addressed. Herbal medicine is used to treat many conditions, such as allergies, asthma, premenstrual syndrome, chronic fatigue, rheumatoid arthritis, cancer and many more. Different herbs act on different systems of the body. One should know the proper way of using them as medicine or it is advisable not to use them without consulting an experienced ayurvedic physician. Presently, the 151 herbs of Punjab (India) belonging to different families, their common name and the role played by them and their importance in curing different health problems or diseases is summarized.

Introduction Fruit extract of Tribulus terrestris (TT) bears aphrodisiac and antioxidative properties. Antimicrobial drug, metronidazole (MTZ) impairs the spermatogenic activity and fertility in males. Objective Validation of the use of fruit extract of TT as a supplement against MTZ-induced fertility impairment in males. Methods Adult Swiss strain male mice were administered with 500mg/kgBW/day of MTZ for 28 days. Low (100mg/kgBW/day) and high (200mg/kgBW/day) doses of TT were administered simultaneously with MTZ (500mg/kgBW/day) for same duration. All males were cohabited with virgin proestrus females. Vaginal plug formation was observed to calculate the libido index. Cohabited females were sacrificed on fifteenth day of gestation to dissect out the ovaries and uteri. Fertility index, quantal pregnancy, pre-implantation and post-implantation losses were calculated. Results MTZ-treated males showed unaltered mating ability, however, the females impregnated by such males exhibited marked alterations in the fertility index, quantal pregnancy and pre- and post-implantation losses. Supplementation with low dose of TT failed to restore such reproductive toxicities exhibited by administration of MTZ. However, the altered reproductive toxicities were reinstated to control values following supplementation with high dose of TT. Conclusion The fruit extract of TT may emerge as an effective herbal remedy, correcting the drug-induced fertility impairments in males.

Since the beginning of civilization, and perhaps as early as Neanderthal man, people have used plants as medicine. Evidence indicates that people used plants to cure themselves, e.g. Chinese Emperor (2800 BC); Babylon (1770 BC); Ancient Egypt (1550 BC). Islamic and Indian physicians also wrote many works prior to 1100 AD and the Seals from the Harappan site in Pakistan (2000 BC) also indicate use of plants. New aspects of medicinal plants need to be studied. For example, we should address the question "why plant diversity declines, when plants with weedy traits become more abundant". This is consequently followed by, species that have traits permitting their persistence in degraded and speciespoor ecosystems which are likely to carry high pathogen and vector burdens. Indigenous communities of Pakistan play a vital role in conservation of medicinal plants. Intentionally or unintentionally, people have evolved strategies for doing so in the form of rituals, beliefs and taboos. Various traditional harvesting methods described in one of the study suggest that they were efficient to utilize the natural resources. Our efforts are towards not only providing food security, nutrition and health care to the tribal people, but also to recover, record and diffuse local botanical knowledge and wisdom.

Tribulus terrestris is well known for its medicinal importance in curing urino-genital disorders. Amplified fragment length polymorphism (AFLP), selec-tive amplification of microsatellite polymorphic loci (SAMPL), inter-simple sequence repeat (ISSR) and ran-domly amplified polymorphic DNA (RAPD) markers were used for the first time for the detection of genetic poly-morphism in this medicinal herb from samples collected from various geographical regions of India. Six assays each of AFLP and SAMPL markers and 21 each of ISSR and RAPD markers were utilized. AFLP yielded 500 scorable amplified products, of which 82.9% were polymorphic. SAMPL primers amplified 488 bands, 462 being poly-morphic (94.7%). The range of amplified bands was 66 [(TC) 8 G + M-CAG] to 98 [(CA) 6 AG + M-CAC] and the percentage polymorphism, 89.9 [from (CT) 4 C (AC) 4 A + M-CTG] to 100 [from (GACA) 4 + M-CTA]. The ISSR primers amplified 239 bands of 0.4–2.5 kb, 73.6% showed polymorphism. The amplified products ranged from 5 to 16 and the percentage polymorphism 40–100. RAPD assays produced 276 bands, of which 163 were polymorphic (59%). Mantel test employed for detection of goodness of fit established cophenetic correlation values above 0.9 for all the four marker systems. The dendrograms and PCA plots derived from the binary data matrices of the four marker systems are highly concordant. High bootstrap values were obtained at major nodes of phenograms through WINBOOT software. The relative efficiency of the four molecular marker systems calculated on the basis of multiplex ratio, marker index and average heterozygosity revealed SAMPL to be the best. Distinct DNA finger-printing profile, unique to every geographical region could be obtained with all the four molecular marker systems. Clustering can be a good indicator for clear separation of genotypes from different regions in well-defined groups that are supported by high bootstrap values.

An HPLC-ESI-MS method in a positive mode is proposed to qualitatively analyse the saponin fractions from dietary supplements ofTribulus terrestris L. This method allows for theseparation of structural isomers, as highlighted for some terrestrosines. The MS fragmentation pattern resulted diagnostic to collect structural information and the characteristic loss of water from some furostanolic saponins was highlighted for the first time. Due to the wide number of glycosidic furostanolic and spirostanolic saponins extracted from tribulus, a complete reference “molecular weight map” was created. Finally, a seml-quantitative evaluation of the total saponin content was carried cut by HPLC-MS using protodioscin as external standard.

The effectiveness of an androgenic nutritional supplement designed to enhance serum testosterone concentrations and prevent the formation of dihydrotestosterone and estrogen was investigated in healthy 3 to 58 year old men. Subjects were randomly assigned to consume a nutritional supplement (AND-HB) containing 300-mg androstenediol, 480-mg saw palmetto, 450-mg indole-3-carbinol, 300-mg chrysin, 1,500 mg gamma-linolenic acid and 1.350-mg Tribulus terrestris per day (n = 28), or placebo (n = 27) for 28 days. Subjects were stratified into age groups to represent the fourth (30 year olds, n = 20), fifth (40 year olds, n = 20) and sixth (50 year olds, n = 16) decades of life. Serum free testosterone, total testosterone, androstenedione, dihydrotestosterone, estradiol, prostate specific antigen and lipid concentrations were measured before supplementation and weekly for four weeks. Basal serum total testosterone, estradiol, and prostate specific antigen (PSA) concentrations were not different between age groups. Basal serum free testosterone concentrations were higher (p < 0.05) in the 30- (70.5 +/- 3.6 pmol/L) than in the 50 year olds (50.8 +/- 4.5 pmol/L). Basal serum androstenedione and dihydrotestosterone (DHT) concentrations were significantly higher in the 30- (for androstenedione and DHT, respectively, 10.4 +/- 0.6 nmol/L and 2198.2 +/- 166.5 pmol/L) than in the 40- (6.8 +/- 0.5 nmol/L and 1736.8 +/- 152.0 pmol/L) or 50 year olds (6.0 +/- 0.7 nmol/L and 1983.7 +/- 147.8 pmol/L). Basal serum hormone concentrations did not differ between the treatment groups. Serum concentrations of total testosterone and PSA were unchanged by supplementation. Ingestion of AND-HB resulted in increased (p < 0.05) serum androstenedione (174%), free testosterone (37%), DHT (57%) and estradiol (86%) throughout the four weeks. There was no relationship between the increases in serum free testosterone, androstenedione, DHT, or estradiol and age (r2 = 0.08, 0.03, 0.05 and 0.02, respectively). Serum HDL-C concentrations were reduced (p < 0.05) by 0.14 mmol/L in AND-HB. These data indicate that ingestion of androstenediol combined with herbal products does not prevent the formation of estradiol and dihydrotestosterone.

Tribulus terrestris is a natural herb used for treating many diseases including hypertension. According to previous reports, aqueous extract of tribulus fruits may have some antihypertensive effect with an unknown mechanism. The present study investigated the antihypertensive mechanism of tribulus in 2K1C hypertensive rats by measurement of circulatory and local ACE activity in aorta, heart, kidney and lung. Four groups of rats were selected; control, sham, operated or hypertensive and tribulus treated hypertensive group. Hypertension was induced using silver clip on renal artery by surgery. Four weeks after surgery, a single daily dose of 10 mg/kg of lyophilized aqueous extract of tribulus fruit were given orally to 2K1C rats for four weeks. ACE activity was determined by high performance liquid chromatography (HPLC). Blood pressure was measured by the tail-cuff method. The systolic blood pressure (SBP) was significantly increased in 2K1C rats compared to control rats. The SBP of tribulus fed hypertensive rats was significantly decreased compared to hypertensive rats. The ACE activity in all tissues of 2K1C rats including: aorta, heart, kidney, lung as well as serum were significantly increased compared to normal rats. The ACE activity in all tissues of tribulus fed hypertensive rats was significantly lower than that of hypertensive rats, which was more pronounced in kidney. These results indicated that there is a negative correlation between consumption of tribulus and ACE activity in serum and different tissues in 2K1C rats.

The steroidal saponins of Tribulus terrestris L. (Zygophyllaceae) are considered to be the factor responsible for biological activity of products derived from this plant. The activity depends on the concentration and the composition of active saponins, which in turn is influenced by the geographical origin of plant material. Samples of T. terrestris collected in Bulgaria, Greece, Serbia, Macedonia, Turkey, Georgia, Iran, Vietnam and India were analyzed by LC-ESI/MS/MS for the presence and the concentration of protodioscin (1), prototribestin (2), pseudoprotodioscin (3), dioscin (4), tribestin (5) and tribulosin (6). The flavonoid rutin (7) was also included in the comparison. The results revealed distinct differences in the content of these compounds depending on region of sample collection, plant part studied and stage of plant development. The samples from Bulgaria, Turkey, Greece, Serbia, Macedonia, Georgia and Iran exhibited similar chemical profile and only some quantitative difference in the content of 1-7 with protodioscin (1) and prototribestin (2) as main components. The Vietnamese and Indian samples exhibit totally different chemical profile. They lack 2 and 5, while tribulosin (6) is present in high amounts. Compounds different from 1 to 7 are dominating in these 3 samples. The presented results suggested the existence of one chemotype common to the East South European and West Asian regions. Most probably, the Vietnamese and Indian samples belong to other chemotypes which are still to be studied and characterized. No clear correlation between the burrs morphology and the chemical composition of the samples has been found.

Successive extracts of Tribulus terrestris prepared using petroleum ether, chloroform, 50% methanol and water were tested for anthelmintic activity in-vitro using the nematode Caenorhabditis elegans. The activity could be detected only in 50% methanol extract which on further bioactivity guided fractionation and chromatographic separation yielded a spirostanol type saponin, tribulosin and β-sitosterol-D-glucoside. Both the compounds exhibited anthelmintic activity with ED50 of 76.25 and 82.50 μg/ml respectively.

Crystalloid material soluble in acetic acid was isolated from the bile of lambs with alveld (a hepatogenous photosensitization disease which develops after grazing Narthecium ossifragum). The main components of these bile extracts were shown by hydrolysis, GC-MS, TLC, LSIMS, H-1 and C-13 NMR, and X-ray analysis to be salts of a 4:1 mixture of episarsasapogenin beta-D-glucuronide (1) and epismilagenin beta-D-glucuronide (2). The C-13 NMR spectrum of 1 was fully assigned by comparison with the NMR spectra of model compounds. A metabolic route for conversion of the sarsasapogenin saponins of N. ossifragum into 1 is proposed. Saponins were extracted from the foliage of N. ossifragum, Tribulus terrestris, and Panicum miliaceum. The saponins were hydrolyzed to sapogenins, which were examined by NMR spectroscopy and GC-MS. P. miliaceum afforded a 4:1 mixture of diosgenin and yamogenin, T. terrestris gave a 5:1 mixture of diosgenin and tigogenin, and N. ossifragum yielded a mixture (82:9:5:4) of sarsasapogenin, smilagenin, yamogenin, and another spirostanol, tentatively identified as neotigogenin.

The aim of this study was to investigate the pleotropic effects of an extract of a traditional herb, Tribulus terrestris (TT), on the lipid profile and vascular endothelium of the abdominal aorta in New Zealand rabbits fed a cholesterol-rich diet. Eighteen rabbits were randomly divided into three groups (n=6 for each). One experimental group (EG-I) was given a cholesterol-rich diet, a second experimental group (EG-II) was treated with TT following a cholesterol-rich diet, and a control group (CG) was fed a standard diet. Blood samples were collected on day 0 and then at weeks 4 and 12 to determine total serum cholesterol (TC), high density lipid-cholesterol (HDL-C), low density lipid-cholesterol (LDL-C) and triglyceride (TG) levels. Tissues were collected from the abdominal aorta for immunohistochemistry and transmission and scanning electron microscopy. In EG-II, the serum lipid profile was significantly lower than that of EG-I at week 12 with a reduction of TC: 65%; LDL-C: 66%; HDL-C: 64%; TG: 55%. Ultrastructural analysis revealed that endothelial damage was more prominent in EG-I compared to EG-II. The ruptured endothelial linings and damaged cellular surfaces increased in EG-I compared to EG-II. Our data indicate that dietary intake of TT can significantly lower serum lipid profiles, decrease endothelial cellular surface damage and rupture and may partially repair the endothelial dysfunction resulting from hyperlipidemia.

The availability of detailed environmental data, together with inexpensive and powerful computers, has fueled a rapid increase in predictive modeling of species environmental requirements and geographic distributions. For some species, detailed presence/absence occurrence data are available, allowing the use of a variety of standard statistical techniques. However, absence data are not available for most species. In this paper, we introduce the use of the maximum entropy method (Maxent) for modeling species geographic distributions with presence-only data. Maxent is a general-purpose machine learning method with a simple and precise mathematical formulation, and it has a number of aspects that make it well-suited for species distribution modeling. In order to investigate the efficacy of the method, here we perform a continental-scale case study using two Neotropical mammals: a lowland species of sloth, Bradypus variegatus, and a small montane murid rodent, Microryzomys minutus. We compared Maxent predictions with those of a commonly used presence-only modeling method, the Genetic Algorithm for Rule-Set Prediction (GARP). We made predictions on 10 random subsets of the occurrence records for both species, and then used the remaining localities for testing. Both algorithms provided reasonable estimates of the species’ range, far superior to the shaded outline maps available in field guides. All models were significantly better than random in both binomial tests of omission and receiver operating characteristic (ROC) analyses. The area under the ROC curve (AUC) was almost always higher for Maxent, indicating better discrimination of suitable versus unsuitable areas for the species. The Maxent modeling approach can be used in its present form for many applications with presence-only datasets, and merits further research and development.

Further studies on the constituents of the fruits of Tribulus terrestris led to the isolation of six new furostanol saponins, 26-O-β- d-glucopyranosyl (25R)-furostane-2α,3β,22α,26-tetrol-3-O-β-d-glucopyranosyl (1–4)-β-d-galactopyranoside, 26- O-β-d-glucopyranosyl (25R,S)-5α-furostane-2α,3β,22α,26-tetrol-3-O-β-d-galactopyranosyl(1–2)-β-d- glucopyranosyl(1–4)-β-d-galactopyranoside, 26-O-β-d-glucopyranosyl (25R,S)-5α-furostane-3β,22α,26-triol-3- O-β-d-galactopyranosyl(1–2)-β-d-glucopyranosyl(1–4)-β-d-galactopyranoside, 26-O-β-d-glucopyranosyl (25 R,S)-5α-furostan-12-one-3β,22α,26-triol-3-O-β-d-galactopyranosyl(1–2)-β-d-glucopyranosyl (1–4)-β-d- galactopyranoside, 26-O-β-d-glucopyranosyl (25R,S)-furost-5-ene-3β,22α,26-triol-3-O-β-d-galactopyranosyl(1–2)- β-d-glucopyranosyl(1–4)-β-d-galactopyranoside, 26-O-β-d-glucopyranosyl (25R)-5α-furost-20(22)-en-12-one-3β,26- diol-3-O-β-d-galactopyranosyl(1–2)-β-d-glucopyranosyl(1–4)-β-d-galactopyranoside, named terrestrosin F—K, respectively. The structures were elucidated on the basis of spectroscopic studies of the isolated compounds and their hydrolysed products.

Twenty-five flavonoid glycosides were detected in Tribulus pentandrus and T. terrestris. The glycosides belong to the common flavonols, kaempferol, quercetin and isorhamnetin, with the 3-gentiobiosides as the major glycosides. Traces of a flavone (tricin) glycoside was also present in T. pentandrus. The separation of Tribulaceae as a distinct family from Zygophyllaceae is discussed.

Fresh, mature, ungrazed Tribulus terrestris plant material was subjected to a standard alkaloid extraction procedure. The extract was fractionated by thin layer chromatography (TLC) and high performance liquid chromatography (HPLC). Two major alkaloid fractions were demonstrated. These fractions were identified by means of TLC, ultraviolet spectrofluorimetry (UVS) and HPLC, as the beta-carboline indoleamines harmane and norharmane. The extractable alkaloid content was determined to be 44 mg/kg dry matter. Synthetic harmane and norharmane were administered subcutaneously to sheep at a dose rate of 54 mg/kg. Both compounds caused similar nervous effects. The main effect observed was limb paresis, which in some sheep was body side blased. The clinical signs observed in the experimental sheep were consistent with those described for naturally occurring cases of Tribulus terrestris staggers. It was proposed that harmane and norharmane accumulate in tryptamine-associated neurones of the central nervous system, during months of tribulus ingestion, and gradually interact irreversibly with a specific neuronal gene DNA sequence.

In addition to hecogenin 3-O-beta-D-glucopyranosyl(1--> 4)-beta-D-galactopyranoside, two new steroidal saponins were isolated from the aerial parts of Tribulus terrestris L. On the basis of chemical and spectroscopic evidence, especially 2D NMR spectroscopic techniques, the structures of the new saponins were established as 26-O-beta-D-glucopyranosyl-3-O-[-beta-D-xylopyranosyl(1--> 3)--beta-D-galactopyranosyl(1-->2)--beta-D-glucopyranosyl (1--> 4)-beta-D-glucopyranosyl]-5 alpha-furost-20(22)-en-12-one-3 beta,26-diol and 26-O-beta-D-glucopyranosyl-3-O-[{beta-D-xylopyranosyl (1-->3)--beta-D-galactopyranosyl(1-->2)--beta-D-glucopyranosyl(1 -->4)-beta-D-glucopyranosyl]-5 alpha-furostan-12-one-3 beta,22,26-triol.

By activity-guided fractionation, three known steroidal saponins, prosapogenin A of dioscin, dioscin and gracillin, were isolated from the total saponin fraction of Dioscorea coiletti var. hypoglauca as active compounds causing morphological abnormality of Pyricularia oryzae mycelia. The compounds also exhibited cytotoxic activity against the cancer cell line K562 in vitro. The structures of the compounds were elucidated on the basis of chemical evidence and IR, FAB-MS, 1H-NMR, 13C-NMR, and two-dimensional NMR (2D-NMR) analysis.

Tribulus terrestris L. is an annual plant which has been commonly used in folk medicine as diuretic and against colic pains, hypertension and hypercholesterolemia in Turkey. This study investigated the effects of liophilized saponin mixture of this plant on several smooth muscle preparations in vitro. The liophilized material was obtained from dried and powdered T. terrestris L. by specific extraction method for saponins. Median lethal dose (LD50) of saponin mixture on Swiss albino mice was calculated according to Litchfield-Wilcoxon method via i.p. route. LD50 and its 95% confidence limits were 813 and 739-894 mg.kg-1 respectively. Saponin mixture has caused a significant decrease on peristaltic movements of isolated sheep ureter and rabbit jejunum preparations in a dose-dependent manner (p < 0.05). However it has been observed no effect on isolated rabbit aorta and its contractile response to KCl or noradrenaline (p > 0.05). According to these results it has been suggested that T. terrestris L. or its saponin mixture may be useful on some smooth muscle spasms or colic pains.

A rapid 96-well plate assay using sulphorhodamine B (SRB) protein stain for cell number has been adopted to screen herbs used in traditional treatments of vitiligo for substances capable of stimulating melanocyte proliferation. Its applicability to melan-a cells, a mouse pigmented cell line, has been validated. SRB assay produced good linearity up to 11 x 10(4) cells/well and interference by melanin present in the cells accounted for less than 10% of the total optical density readings. The intra-assay variation was small but interassay variation was marked. For better assay precision, it is recommended that the results to be compared should be performed on the same day and controls should be plated in the same experiment, ideally in the same plate. Optimum conditions for exponential melan-a cell growth were established: viz. initial plating density (3-8 x 10(3) cells/well), incubation period (4 days) and foetal bovine serum concentration (5%). Under these conditions cells were responsive to the mitogen tetradecanoyl phorbol acetate (TPA). Out of 28 herbal extracts screened in this assay, significant stimulation (P < 0.05) of melanocyte proliferation was observed, in the absence of TPA, using aqueous extracts of Astragalus membranaceous root, Citrus reticulata peel, Dictamnus dasycarpus root bark. Ophiopogon japonicus root, Poria cocos sclerotium and Tribulus terrestris fruit.

The objective of the present study was to investigate the effect of oral treatment of Tribulus terrestris (TT) extract on the isolated corpus cavernosal tissue of New Zealand white (NZW) rabbits and to determine the mechanism by which protodioscin (PTN), a constituent of the TT, exerts its pharmacological effects. Twenty-four NZW rabbits were randomly assigned to 4 experimental groups of 6 each. Group I served as control. Groups II to IV were treated with the extract at different dose levels, i.e. 2.5 mg/kg, 5 mg/kg and 10 mg/kg body weight, respectively. The TT extract was administered orally, once daily, for a period of 8 weeks. The rabbits were then sacrificed and their penile tissue isolated to evaluate the responses to both contracting and relaxing pharmacological agents and electrical field stimulation (EFS). PTN on its own had no effect on the isolated corpus cavernosal strips. The relaxant responses to EFS, acetylcholine and nitroglycerin in noradrenaline precontracted tissues from treated groups showed an increase in relaxation of a concentration dependent nature compared to that of the tissues from control group. However, the contractile, anti-erectile response of corpus cavernosal tissue to noradrenaline and histamine showed no significant change between the treatment and the control groups. The relaxant responses to acetylcholine, nitroglycerin and EFS by more than 10%, 24% and 10% respectively compared to their control values and the lack of such effect on the contractile response to noradrenaline and histamine indicate that PTN has a proerectile activity. The enhanced relaxant effect observed is probably due to increase in the release of nitric oxide from the endothelium and nitrergic nerve endings, which may account for its claims as an aphrodisiac. However, further study is needed to clarify the precise mechanism of its action.

Traditional herbs have been a revolutionary breakthrough in the management of erectile dysfunction and have become known world-wide as an 'instant' treatment. The modern view of the management of erectile dysfunction subscribes to a single etiology, i.e. the mechanism of erection. A large number of pharmacological agents are orally consumed and vasoactive agents inserted intraurethrally or injected intrapenially to regain good erection. Modern phytochemicals have developed from traditional herbs. Phytochemicals focus their mechanism of healing action to the root cause, i.e. the inability to control the proper function of the whole body system. Hence phytochemicals manage erectile dysfunction in the frame of sexual dysfunction as a whole entity. Protodioscin is a phytochemical agent derived from Tribulus terrestris L plant, which has been clinically proven to improve sexual desire and enhance erection via the conversion of protodioscine to DHEA (De-Hydro-Epi-Androsterone). Preliminary observations suggest that Tribulus terrestris L grown on different soils does not consistently produce the active component Protodioscin. Further photochemical studies of many other herbal plants are needed to explain the inconsistent results found with other herbal plants, such as in diversities of Ginseng, Eurycoma longifolia, Pimpinella pruacen, Muara puama, Ginkgo biloba, Yohimbe etc.
