INTRODUCTION
Salacia chinensis Linn. (Synonyms: Salacia prinoides)
Family: Celastraceae (Spike-thorn family) commonly
called as Saptrangi, Dimal, Modhupal, Ingli, Cherukuranti,
Nisul-bondi. This is a small erect or straggling tree or
large, woody, climbing shrub found almost throughout
India including Andaman and Nicobar Islands (Mehra and
Handa, 1969).
MATERIALS AND METHODS
Three species of Salacia that is, S. chinensis, Salacia reticulate,
Salacia oblonga are used traditionally in Ayurveda, Unani systems
as antidiabetic agent. Preclinical research and isolated clinical trials
studying these effects have been promising. Fruits and Roots are
the useful parts. Ripe fruits are eaten. Roots have been used as an
antidiabetic drug. S. chinensis have been used in India and in other
countries as a tonic, blood purifier and to treat amenorrhea and
dysmenorrhea. Its root bark was used in gonorrhoea, rheumatism
and skin diseases. Its aqueous extract showed significant
hypoglycemic activity. Root bark boiled in oil or as decoction or as
powder is used for the treatment of rheumatism, gonorrhoea,
itches, and asthma, thirst and ear diseases (Encyclopedia of World
Medicinal Plants. Vol.1. 1713: 2418; Almeida and Almeida, 1994;
Singh and Duggal, 2010; Mehra and Handa, 1967). The root is dark
yellow externally and light yellow internally. It has characteristic
odor and bitter in taste. The TS of root (Figure 1) shows wavy cork,
cortex consisting of brown matter, uniserriate and few biserriate
medullary rays and vascular bundle consists mainly of secondary
xylem and phloem. Pith, Pericycle and endodermis is absent.
Starch is present in the cortex region. The standardization

parameters like ash value and extractive value have been also
studied. The ash value results for this plant are Total ash
4.825%w/w; Water-soluble ash 2.75%w/w, Acid-insoluble ash
3.5%w/w. The extractive value results are found to be 3.275%w/w
in Water-s oluble extractive value and 1.8%w/w in Alcohol-soluble
extractive value (Dholwani et al., 2009). Table 1 is showing
Fluorescence analysis of root powder.
RESULTS
The roots contains the phytoconstituents like alkaloides,
glycosides, polyphenols, flavanoides, coumarins,
proteins, carbohydrates, gums and mucilage, fixed oil
and volatile oil. Triterpenoids like lupanes, hopanes,
friedelanes are abundant in root and stem of plant.
Salacinol from the stems of S. chinensis was found to
alpha- glucosidase inhibitor. Mangiferin showed inhibitory
effect on rat lense aldose reductase. Figure 2 and Table
2 has given idea about chemical composition of salacia
roots.
Recent studies have demonstrated that Salacia roots
are very useful in type 2 diabetes and obesity-associated
hyperglycemia, dyslipidemia and related cardiovascular
complications and it may be due to the fact that it
modulate multiple targets (Yuhao et al., 2008) like
peroxisome proliferator-activated receptor-alpha-
mediated lipogenic gene transcription, angiotensin
II/angiotensin II type 1 receptor, alpha-glucosidase,
aldose reductase and pancreatic lipase. These activities
are due to the constituentslike mangiferin, salacinol,
kotalanol and kotalagenin 16-acetate (Yoshikawa et al.,

Clinical trial studies have also been carried out to confirm
the effects. Table 3 is explaining the all activities of
salacia roots.
Conclusion
S. chinensis is a traditional South and Southeast Asian
herb medicine and has been reported to have an
antidiabetic function through α-glucosidases inhibitory
activity. The various active constituents have been found
to affect multiple targets in diabetes, obesity and
associated cardiovascular diseases through modulating
PPAR-α-mediated lipogenic gene transcription and
angiotensin II/angiotensin II type 1 receptor, inhibiting α-
glucosidase, aldose reductase and pancreatic lipase.
Although toxicological studies have suggested minimal
adverse effects of this plant in rodents, a clinical trial is
crucial to further confirm the safety of Salacia roots. In
addition, mechanistic studies are necessary in order to
know drug interaction of Salacia root with other

Objective: Salacia chinensis and Woodfordia fruticosa are medicinal plants from the Western Ghats of India traditionally used in the treatment of diabetes, diarrhea and worm infections. The current study aims to evaluate the cytotoxic potential of methanolic extract of Salacia chinensis and Woodfordia fruticosa against breast and pancreatic cancers. Methods: Methanolic extract of dried leaves of Salacia chinensis and Woodfordia fruticosa were obtained by Soxhlet extraction. The cytotoxic potential of the dried extract was evaluated against human breast (MDA-MB-231) and pancreatic (PANC-1) cancers in vitro using MTT-based assay. Results: The study showed a dose-dependent cytotoxicity of Salacia chinensis and Woodfordia fruticosa leaf extracts against breast and pancreatic cancers with IC50 values of 124 μg/ml against MDA-MB-231 and 230.5 μg/ml against PANC–1 cells, respectively. Conclusion: Results indicate the presence of cytotoxic phytochemicals in Salacia chinensis and Woodfordia fruticosa. Further purification of the extract might be beneficial to isolate the anticancer phytochemical.

Bacterial endophytes are found in the internal tissues of plants and have intimate associations with their host. However, little is known about the diversity of medicinal plant endophytes (ME) or their capability to produce specialised metabolites that may contribute to therapeutic properties. We isolated 75 bacterial ME from 24 plant species of the Western Ghats, India. Molecular identification by 16S rRNA gene sequencing grouped MEs into 13 bacterial genera, with members of Gammaproteobacteria and Firmicutes being the most abundant. To improve taxonomic identification, 26 selected ME were genome sequenced and average nucleotide identity (ANI) used to identify them to the species-level. This identified multiple species in the most common genus as Bacillus. Similarly, identity of the Enterobacterales was also distinguished within Enterobacter and Serratia by ANI and core-gene analysis. AntiSMASH identified non-ribosomal peptide synthase, lantipeptide and bacteriocin biosynthetic gene clusters (BGC) as the most common BGCs found in the ME genomes. Five of the ME isolates belonging to Bacillus, Serratia and Enterobacter showed antimicrobial activity against the plant pathogen Pectobacterium carotovorum. Using molecular and genomic approaches we have characterised a unique collection of endophytic bacteria from medicinal plants. Their genomes encode multiple specialised metabolite gene clusters and the collection can now be screened for novel bioactive and medicinal metabolites.

Salacia chinensis (SC) is generally known as Saptrangi, which has been used as an herb in Ayurvedic medicine and has a broad range of biological applications. The current research was planned to develop Salacia chinensis-loaded gold nanoparticles (SC-AuNPs) and to assess the anti-obesity parameters in a high-fat diet (HFD) treated obese rats. SC-AuNPs were synthesized and characterized using UV-visible spectroscopy, SEM, FTIR, EDX, XRD, and TEM. Furthermore, the bodyweight changes, BMI, adipose index, leptin, resistin, adiponectin, AI, CRI, liver marker enzymes, inflammatory markers, lipid profile, AMPK signaling proteins, and liver histopathological changes were analyzed. We observed that the synthesized SC-AuNPs had a spherical shape, crystalline nature, and possessed a different functional group. The SC-AuNPs treatments also decreased body weight, BMI, adipose index, leptin, resistin, AI, CRI, liver marker enzymes, lipid profile, inflammatory markers, and AMPKα1. On the other hand, SC-AuNPs treatment increased adiponectin, HDL-C, and pAMPKα1. The histopathological findings showed improved result with reduced hepatocyte degradation under the influence of SC-AuNPs treatment.

Diabetes mellitus is a chronic metabolic disorder which is commonly found life-threatening disease and it continuously reducing the life expectancy. It is characterized by hyperglycaemia (raised blood sugar level) resulting from defects in insulin secretion, action, or both. Since thousands of years, medicinal plants are being used by our ancestors for the prevention, treatment or even cure the diabetes mellitus. Utilization of these herbal plants is increasing rapidly last two to three decades due to their lesser toxicity and cost effectiveness property as compared to synthetic drugs. In this review, approximately 30 medicinal plants were described which are native to India and traditionally used by the people living in shivalik range of Himalaya in Uttarakhand (specially Dehradun & Haridwar) for the treatment of diabetes mellitus. The data about these plants was collected from science direct, PubMed, web of science, scopus, mdpi, google scholar and different other search engines and websites. This review was conferred in a systematic way as it includes botanical name, family, vernacular name, parts used and pharmacological uses of plants in a tabulated form. There are various scientific evidences behind the uses of some medicinal plants which have been mentioned along with the summary of individual medicinal plant. In this review, all the plants and herbs are easily available in these regions of Uttarakhand and local people traditionally uses these plants as vegetable, seasoning, flavouring and usually consume as a part of their diet. There are some limitations of phytotherapy which limit it to completely replace the allopathic therapy as less bioavailability, less rate of absorption and slow rate of dissolution. But by using various advanced dosage forms (phytosomes, neosomes, liposomes, nanoparticles, nanobubbles, nano diamonds, nanosphere etc.) and method of delivery (various invasive and non-invasive methods) which can bypass these all problems associated with the potency and efficacy of phytochemicals.

Dried stems of Salacia chinensis were chopped and boiled with filtered water. The clear solution was collected and partition extracted with n-butanol. The nbutanol fraction (S. chinensis extract) was evaporated and followed by lyophilization. The S. chinensis extract was investigated for hypotensive activity in anesthetized female rats in estrus, and for vasodilator activities on isolated thoracic aortic rings in vitro. Results showed that intravenous injection of S. chinensis extract (4-120 mg/kg) caused a decrease in mean arterial blood pressure and heart rate of anesthetized rats in a dose-dependent manner. These effects were not blocked by atropine, a muscarinic receptor antagonist or propranolol, a β-adrenergic receptor antagonist. For the in vitro preparation, the S. chinensis extract (0.01-0.3 mg/ml) caused vasodilatation of the thoracic aortic rings pre-constricted with phenylephrine in a dose-dependent manner. These effects persisted in the presence of atropine, propranolol or both of atropine and propranolol. However, when N G-nitro-Larginine, a nitric oxide synthase inhibitor, was added or removal of vascular endothelium, the vasodilator activity of the S. chinensis extract on the thoracic aortic ring disappeared. These results suggest that the n-butanol extract from stems of Salacia chinensis possesses a hypotensive effect. The mechanism involved may be an indirect effect by stimulated release of nitric oxide from vascular endothelial cells and causes vasodilatation.

Salacia prenoides or S.chinensis belonging to the family Hippocrateaceae is a climbing shrub known as saptarangi in Ayurveda. The roots of this plant is repoted to possess various medicinal uses as antidiabetic, astringent and abortificient. The pharmacognostical study of roots of this plant has not been reported. Therefore, the present investigation was planned to study the morphology, microscopy, physicochemical parameters, phytochemical screening and HPTLC study of roots of Salacia prenoides.

The salacia species (Celastraceae), including S chinensis, S reticulata, and S oblonga, are used as antidiabetic agents in traditional systems of medicine such as Ayurveda and Unani. The plants have been used in India, Japan, and Korea to treat high blood glucose levels. Preclinical investigations have demonstrated antiobesity activity of salacia, warranting large-scale clinical studies. Isolated clinical trials have, thus far, supported this claim. This review summarizes pharmacological investigations of various species of salacia with respect to diabetes.

From the root bark of Salacia prinoides DC. (Celastraceae), six closely related triterpenes, P, Q, R, S, T and V have been isolated. These have been shown to be 1,3-diketofriedelane derivatives. The structures of these compounds, 1, 10, 39, 33, 11 and 12, have been established on the basis of spectroscopic as well as degradative evidence.

The study was undertaken to evaluate the antihyperglycemic potential of mangiferin purified from methano- lic root extract of Salacia chinensis (S. chinensis )i nc ontrol and streptozotocin (STZ)-induced diabetic rats. The mangiferin was administered orally at a dose of 40 mg/kg weight per day (30 days) to STZ-induced diabetic rats. The mangiferin treated diabetic rats significantly decreased the level of blood glucose, glycosylated hemoglobin as well as increased level of insulin and hemoglobin. The activities of hexokinase, pyruvate kinase, glucose- 6-phosphate dehydrogenase, glycogen synthase, and glycogen content level were increased to near normal in mangiferin treated diabetic rats. The activities of lactate dehydrogenase, glucose-6-phosphatase, fructose-1,6- diphosphatase and glycogen phosphorylase were significantly decreased in liver tissue of diabetic treated rats. These findings demonstrated that mangiferin possess antidiabetic activity against STZ-induced diabetic rats. The antidiabetic effect of mangiferin was compared with standard antidiabetic drug glibenclamide.

Mangiferin, three catechins, and two catechin dimers were isolated from the roots of Salacia reticulata (SRE), and examined their inhibitory activities against several carbohydrate metabolize enzymes (sucrase, maltase, isomaltase, (alpha -amylase, and aldose reductase). Among them, mangiferin was found to inhibit sucrase, isomaltase, and aldose reductase from rat with IC50 values of 87, 216 and 1.4 mug/ml, respectively. The inhibitory activities of mangiferin are competitive for sucrase and isomaltase with inhibitor constant (K-i) 55 mug/ml and 70 mug/ml, respectively. In order to determine the mangiferin contents in the water extracts from the roots of S. reticulata, a quantitative analytical method by means of HPLC was developed and the mangiferin contents in SRE were determined to be in the range of 0.9-2.3% by the application of this method. A high linear correlation (r=0.934) was observed between the mangiferin contents and the sucrase inhibitory activity. In addition, this analytical procedure of mangiferin was found to be applicable for other Salacia species (S. oblonga, S. chinensis, and S. prinoides). Thus, the quantitative HPLC analysis of mangiferin was supposed to be suitable for the quality control of Salacia species and its products.
