    ABSTRACT: Thymus jankae Cel. and Thymus pulegioides L. subsp. montanus (W.K.) Ronn growing wild in Kosovo have been analyzed for their volatile chemical profile using GC-MS technique. The essential oil of the plants was obtained by hydrodistillation with Clevenger apparatus. Essential oil of two samples of T. jankae Cel. resulted with yields of 0.60 % and 0.72 % respectively, while T. pulegioides L. essential oil yield was 1.58 % on dried weight. Exactly fifty-eight compounds were identified in all three samples. Two chemotypes resulted from the studied T. jankae Cel. essential oil samples: thymol chemotype with 45.78 % of thymol, and β-caryophyllene/caryophyllene oxide chemotype, with 33.25 % and 21.83 %, respectively. The chemical profile of the essential oil sample of T. pulegioides L. resulted with geraniol as the main constituent, with 34.52 % in total. Presented results confirm the influence of environmental and phenological conditions on the chemical composition.

    ABSTRACT: The carvacrol is thought to promote optimal health via its antioxidant and free radical scavenging effects. The aim of our present study was to investigate the efficacy of carvacrol on the development of kidney injury in acute pancreatitis model (AP) induced by cerulein and to explore the underlying mechanism. The rats were randomised into groups to receive (I) no therapy;(II.) 50 μg/kg cerulein at 1-h intervals by four intraperitonally injection (i.p.); (III) 50, 100 and 200 mg/kg carvacrol by one i.p.; and (IV) cerulein+carvacrol after 2 h of cerulein injection. 12 h later, serum was providedto assess the blood urea nitrogen (BUN), creatinine (CRE) and uric acid (UA) values. Also, renal tissues were obtained for histological and biochemical measurements. Kidney oxidative stress markers were evaluated bychanges in the amount of lipid peroxides measured as malondialdehyde (MDA) and changes in tissue antioxidant enzyme levels, superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-PX). Histopathological examination was performed using scoring systems. We found that the increasing doses of carvacrol decreased pancreatitis-induced MDA levels. Moreover, the renal SOD, CAT and GSH-Px activities in the AP+carvacrol group were higher than that of the rats in the AP group. In the treatment groups, the BUN, CRE and UA were reduced. Besides, necrosis, coagulation and inflammation in the kidney were alleviated (p <0.05). Finally, the magnitude of the protective effect on kidney is certain, and 200 mg/kg carvacrol is an effective theraphy for oxidative stress caused by AP.

    ABSTRACT: The composition of essential oils obtained from the seeds of Foeniculum vulgare Mill. and Cuminum cyminum L. were analysed using GC and GC-MS. The antimicrobial activities of the essential oils were conducted by disc diffusion method and minimum inhibitory concentration (MIC) by agar dilution method. The essential oils of the seeds of F. vulgare showed maximum zone of inhibition 33 mm against S. typhimurium and 28 mm against E. coli respectively, while C. cyminum showed zone of inhibition 22 mm and 17 mm against S. typhimurium and E. coli respectively. MICs of essential oils were tested at concentration ranging from 2.0 to 0.0075 % (v/v). The F. vulgare essential oil showed lowest MIC values 0.031 and 0.062 % (v/v) against S. typhimurium and E. coli respectively, while C. cyminum showed MIC vaules 0.125 and 0.250 % (v/v) against S. typhimurium and E. coli respectively. The results showed that essential oil of F..vulgare is more effective than C. cyminum and S. typhimurium is more susceptible for the tested spices as compared to E.coli .The GC-MS data showed the main component found in F. vulgare Mill essential oil was identified as trans-anethole (50.4 %), methylchavicol (22.4 %), limonene (11.4 %) and fenchone (11.1 %) whereas γ-terpin-7-al (22.9 %), γ-terpinene (22.6 %), β-pinene (22.2 %) and cuminaldehyde (13.1 %) were the major compounds in C. cyminum L.

    ABSTRACT: The aim of this research was to investigate the influence of time of extraction methods on yield and chemical composition of the essential oil from dark green parts of Allium ampeloprasum and examine their anti-diabetic activity. The essential oil of dark green parts of Egyptian A. ampeloprasum L. which are not edible, and with less flavor, have been isolated by hydro distillations (HD). The compositions of the essential oils were characterized by GC-MS. A total of 35 and 31 compounds were identified, constituting over (87.8 %, 8 h) and (36.4 %, 6 h) of oil composition of A. ampeloprasum L., respectively. Oxygenated monoterpenes were shown to be the main group of volatiles (HD after 8 h, 35.5%). The amount of total volatiles were found to be better in HD of A. ampeloprasum L. which isolated after 8 h. The anti-diabetic activity of the isolated essential oils from green parts of A. ampeloprasum L.was investigated.

    ABSTRACT: Denaei Thyme (Thymus daenensis Celak.) is a perennial plant from Lamiaceae family. The plant's leaves possess biological attributes that provide it with the potential to be used for medicinal purposes and newly for suppressing the growth of herbaceous plants. In this study essential oil (EO) compositions and phytotoxic effects of four T. deanensis ecotypes (ECTPs) of T. deanensis were evaluated on Amaranthus retroflexus, Avena fatua, Datura stramonium and Lepidium sativum germination and related growth traits.For this purpose, thyme plants were collected from different ecological locations of Fars Province, Iran to identify EOs content and compositions and also their phytotoxic activity. Gas chromatography (GC) and GC-Mass spectrometry (GC-MS) analysis of the EOs showed that thymol (20 - 60.5 %) and carvacrol (20.1 - 63.4 %) were the two major oil components found in the studied ECTPs. For evaluating phytotoxic activity, the concentrations, 0, 200, 400, 600, 800 and 1000 µl l-1 of the EOs were tested in vitro against seeds and their effect on germination percentage and rate, root and shoot length, fresh and dry weight of seedlings were determined. In general, higher EO concentration resulted in lower germination percentage and/or rate in all studied species. The overall results of germination test represent a reduction in germination percentage of most species at concentration of 200 µl l-1. The results reported herein suggest that herbicidal properties of the four ECTPs could be due to their EO concentrations and have potential as natural herbicides.

    ABSTRACT: The composition of the essential oil of the leaves and flowers of A. africanus from Nigeria were analyzed by GC-MS. Thirty-two compounds representing 88.7 % of the essential oil were characterized from the leaves parts of A. africanus. The essential oil was dominated by 2-(1,1-dimethylethoxy)-ethanol (22.97 %), caryophyllene oxide (18.56 %), 1,2,4-Trimethylbenzene (10.0 %), 1-Ethyl-1,4-dimethylbenzene (5.76 %) and hexahydrofarnesyl acetone (4.42 %). A total of 35 compounds, representing 93.9 % of the total oil were identified from flowers parts of A. africanus. The major constituents were caryophyllene oxide (51.6 %), β-caryophyllene (5.70 %), humulene-1,2-epoxide (5.43 %) and geranylacetone (4.32 %). The antioxidant potential of the leaves and flowers essential oils of A. africanus was determined on the basis of scavenging activity of the stable 1,1-diphenyl-2-picryl hydrazyl (DPPH) free radical. The percentage inhibitions of the leaves and flowers essential oils were 50.01 and 58.49 % respectively higher than 13.84 % for the positive control, ascorbate. The results provide a support for the use of this plant in traditional medicine for possessing considerable therapeutic potential. The results also supported further studies on A. africanus.

    ABSTRACT: Essential oil extracted by hydrodistillation from Iranian Carum copticum was characterized by means of GC-MS. In the case of C. copticum, ten compounds were identified representing the 94.1 % of the total oil with a yield of 0.91 % w/w. The major constituents of the oil were described as p-cymene (11.03 %), γ-terpinene (20.0 %) and thymol (45.6 %). The essential oil was also subjected to antimicrobial, antioxidant and antiinflammatory activities. The essential oil was particularly active against Candida parapsilosis, with the lowest MIC and MBC value (1.5±0.11 and 1.5±0.10 mg/ml). Furthermore, the essential oil and its main compounds showed a potent NO scavenging effect and inhibited inducible NO synthase expression. These results support the use of the essential oil and its main compounds for their anti-inflammatory properties and antimicrobial activity.

    ABSTRACT: The essential oil from the aerial parts of Ocimum canum grown in Togo was extracted by steam distillation. An analysis using Gas Chromatography (GC) and Gas Chromatography-Mass spectrometry (GC-MS) was carried to determine the oil percentage composition and to investigate its in vitro anti-termite activity by inhalation method. The extracted oil contained mainly terpineol-4 (39.40 %), linalool (23.80 %), γ-terpinene (6.70 %), (E)-α-bergamotene (6.20 %) and β-caryophyllene (5.30 %). The in vitro anti-termite activity of the volatile oil and its major components revealed an insecticidal activities on the termite species Macrotermes subhyalinus. At 1 µ.L-1 concentration the extracted oil caused a 100 % mortality of all individuals after 24 hours of exposure. The concentrations of 0.6 and 0.8 µl.L-1 respectively. Terpineol-4 and linalool also caused 100 % mortality after an exposure time of 24 hours. To compare with the commercial pesticide (Dursban) used as positive standard control, just a concentration of 0.6 µl.L-1 was necessary to kill 100 % of the tested termites after an exposure time of 24 hours. Terpineol-4 presented the weakest LD of 0.0628 µl.L-1 compared to Dursban:0.2472 µl.L-1; linalool: 0.2993 µl.L-1 and O. canum oil: 0.4004 µl.L-1. These findings indicated that the tested essential oil and its major components are a potential anti-termite alternatives to synthetic chemical pesticide in the termite control.

    ABSTRACT: Group B streptococci are the cause of dangerous infections both of neonatal and obstetrical sepsis; they also affect pregnant women and elderly patients with chronic underlying medical conditions. The aim of this work was to investigate the antimicrobial activity of cinnamon bark oil obtained from Cinnamomum zeylanicum Ness against clinical strains of group B streptococci. Materials and methods: The antibacterial activity of oil was tested against standard and clinical bacterial strains of Streptococcus agalactiae. The agar dilution method was used to check the inhibition of microbial growth at various concentrations of the cinnamon bark oil. Susceptibility testing to antibiotics was carried out with the use of a disc-diffusion method. The cinnamon bark oil exhibits anti-GBS activity at the very low concentrations. It is also efficacious against MLSb-positive S. agalactiae strains isolated from the anus and vagina of women at 35-37 weeks of pregnancy. Cinnamon bark oil demonstrated a very good antibacterial activity against clinical S. agalactiae strains. It can be used as the alternative to the chemicals administered against GBS isolates.

    ABSTRACT: The effects of oregano, sage and rosemary essential oils on lipid oxidation and color properties of minced beef during refrigerated storage for 10 days were investigated. Minced meats were divided into four treatment groups and were homogenized with 2 % (w/w) of oregano essential oil, sage essential oil and rosemary essential oil separately. Samples in the control treatment had no essential oils added. The results of the present study show that adding essential oils protect minced beef against lipid oxidation and extend the shelf-life of minced meat during refrigerated storage. Oregano, rosemary and sage essential oil treatments demonstrate higher antioxidant activity and L* values when compared to control treatment. Oregano and sage treatment have lower oxidation of minced beef than rosemary and control treatment. Oregano essential oil showed the highest antioxidant activity, when compared to the control and the others groups. In conclusion, the best antioxidative effects were obtained from oregano essential oil.

    ABSTRACT: To investigate the effects of zinc nutritional treatments (1 and 2 mg kg-1 in soil application and 1 and 3 g L-1 in foliar application) and moisture regimes (2, 4 and 8 days irrigation intervals) on growth parameters and essential oil of costmary (Chrysanthemum balsamita L.), a pot experiment was conducted. Growth characteristics were significantly decreased as irrigation intervals were increased. Moreover, essential oil content and yield were significantly increased and reduced under water deficit, respectively. Zinc had an additive effect on growth parameters, essential oil content and yield. Oxygenated monoterpenes (especially carvone) were appointed as the most principle class of essential oil constituents. Regardless of zinc nutrition, the highest and the lowest carvone content were observed in 4 and 8 irrigation intervals, respectively. Zinc had also, additive effect on carvone content. The results showed that the effects of zinc and moisture regimes on oil composition appear to be variable.

    ABSTRACT: Mechanization of threshing and separation of Origanum onites is limited by practical constraints. In this study, we investigated the effects of moisture content on physical and mechanical properties of O. onites to be applied to the design of mechanized threshing and separation operations. Leaf, stalk and flower dimensions, projection area, picking force, leaf-to-stalk ratio, leaf-to-flower ratio, and essential oil content of O. onites were determined at three different moisture contents: 8.9 %, 11.4 %, and 15.0 % (d.b). Most parameters increased linearly with increasing moisture content. The essential oil content of O. onites decreased with increasing moisture content. Moisture content had a significant effect on the physical and mechanical properties of O. onites. Flower picking force of O. onites varied between 3.630 and 4.050 N and Leaf picking force of O. onites varied between 0.375 and 0.974 N. Data on stem diameter are used for designing threshing and separation machinery, while data on flower projection area are required for effective transport, cleaning, and separation of O. onites. Moisture content of O. onites should be optimized to achieve ideal machinery design, as well as energy, power, and cost savings.

    ABSTRACT: The present study describes the potential capabilities of four different extraction techniques, namely hydrodistillation (HD), solvent-free microwave extraction (SFME), microwave assisted hydrodistillation (MWHD) and headspace solid-phase microextraction (HS-SPME) to isolate the essential oils and volatile fractions from the aerial parts of Ferula ovina in combination with analysis by GC and GC-MS. By means of the HD, SFME, MWHD and HS-SPME methods, 14, 30, 20 and 28 components were identified in the chemical profiles, representing 100 %, 95.6 %, 97.4 and 98.2 % of the total compositions, respectively. It was observed that in all of the profiles, monoterpene hydrocarbons constituted the main components while the next most common are oxygenated monoterpenes. In addition, the class order of natural compounds through the HD, SFME and MAHD approaches are the same whereas a slightly difference pattern is observed when using HS-SPME.

    ABSTRACT: Selinum vaginatum C.B. Clarke. (Apiaceae) was collected from two distant populations of north-west Himalaya, India. Underground parts were subjected to hydro distillation in a Clevenger-type apparatus and 0.24-0.27 % essential oil could collect. Twenty eight constituent from the volatile part was identified with GC-FID and GC-MS analysis. Great variations exist in qualitative and quantitative parameters of the essential oil. The study revealed that only nine constituents were common to both populations. Bornyl acetate was major constituents (31-51 %) of the essential oil in both the populations. Second major constituent was α-pinene from Rhohtang whereas β-phellandrene was second major constituents from Tungnath. Existing variations in the essential oil composition may be attributed to environmental factors as well genetic makeup. Such variations are important for assessment of genetic variability and crop improvement program of species.
