This work was undertaken to explore antityrosinase and antioxidant activities of twenty essential oils of edible Thai plants. Antityrosinase activity against mushroom tyrosinase was examined by means of the dopachrome method using L-dopa as an enzymatic substrate. The essential oil of Cymbopogon citratus had the highest level of antityrosinase activity, followed by that of Ocimum canum with enz...
The essential oils of the flowering aerial parts of two Ocimum species viz., Ocimum gratissimum and O. sanctum were analyzed by gas chromatography and gas chromatography/mass spectroscopy. The principal constituent of O. gratissimum and O. sanctum was eugenol (75.1%) and methyl eugenol (92.4%), comprising 99.3 and 98.9% of the total oils, respectively. In vitro antimicrobial activity of the ess...
Ethanol extract of leaves of ocimum sanctum was screened for its antistressor actions against acute and chronic noise stress in albino rats by investigating the plasma corticosterone level in these animals. There was a significant elevation of the corticosterone level in plasma of rats subjected to 30 min noise (100 dB) stress. Chromic exposure (4 hr daily for 30 days) to noise with same intens...
In vivo cytogenetic assay in Allium cepa root tip cells has been carried out to detect the modifying effect of Ocimum sanctum aqueous leaf extract against chromium (Cr) and mercury (Hg) induced genotoxicity. It was observed that the roots post-treated with the leaf extract showed highly significant (p < 0.001) recovery in mitotic index (MI) and chromosomal aberrations (CA) when compared to pre-...
سابقه و هدف: بیوچار به عنوان اصلاح کننده آلی خاک، سبب بهبود ویژگیهای فیزیکی و شیمیایی خاک، افزایش فراهمی عناصر غذایی، کاهش گازهای گلخانهای، کاهش آبشویی عناصر و در نهایت افزایش تولیدات زراعی میشود. تنش رطوبتی نیز یکی از مهمترین عوامل محدود کننده رشد گیاهان است. خاک های مناطق خشک حاوی مقدار کمی مواد آلی بوده و به دلیل پ هاش بالا، با مشکل کمبود عناصر کممصرف روبهرو هستند؛ بنابراین این مطالعه ب...
World health organization (WHO) has advocated the evaluation of therapeutic potential of plants for diseases where we lack safe allopathic drugs. Ocimum sanctum described as sacred and medicinal plant in ancient literature, commonly known as Tulsi is derived from ‘Sanskrit’, which means "the incomparable one". This plant belongs to the family Lamiaceae which is native throughout the Old World t...
The present study was designed to investigate the ameliorative potential of Ocimum sanctum and its saponin rich fraction in chronic constriction injury-induced neuropathic pain in rats. The chronic constriction injury was induced by placing four loose ligatures around the sciatic nerve, proximal to its trifurcation. The mechanical hyperalgesia, cold allodynia, paw heat hyperalgesia and cold tai...
UNLABELLED HISTORY AND OBJECTIVE: The aim of this study was to study the anxiolytic effects of Ocimum sanctum stress-induced anxiety. MATERIALS AND METHODS The study was carried out using male albino rats (200 ± 50 gm), male albino mice (25 ± 100) the effect of O. sanctum evaluated for anxiety and depression using forced swim test FST and rotarod test. RESULTS Restraint stress (3 hours/day ...
In the present study, leaves of Ocimum sanctum, Azadirachta indica and Phyllanthus amarus were collected and the collected leaves were shade dried and powdered by hand crushing. The preparations of different leaves extract was done through modified method. Three different solvents viz., methanol, chloroform and ethyl acetate were used to study the antimicrobial activity of herbal plants. Disc d...
Ocimum sanctum fixed oil showed good antibacterial activity against Staphylococcus aureus, Bacillus pumilus and Pseudomonas aeruginosa, where S. aureus was the most sensitive organism. Sesame and soyabean oils also showed moderate activity against S. aureus. Higher content of linolenic acid in O. sanctum fixed oil could contribute towards its antibacterial activity. The antibacterial activity c...
