To evaluate the anti-inammatory activity of the Ethanolic Extracts of leaves of Averrhoea carambola (EEAC) on experimental animal models. Materials and Methods:The ethanolic extract of Averrhoea carambola leaves was prepared by percolation method using 95% ethanol. For each of the studies four groups of albino ratsof either sex, weighing 100-150g were taken (n = 5). Group A was taken as control, group B and C as test groups, group D as standard. Acute oral toxicity test of the extract was performed as per OECD 425 (OECD Guidelines, 2001). Acute inammation was studied by carrageenan-induced rat paw oedema method and chronic inammation was studied by Freund's complete adjuvant-induced arthritis method. Aspirin 100 mg/kg was taken as a standard drug. Results: The results were analysed by ANOVA followed by Dunnett's multiple comparison test. EEAC at the doses of 200mg/kg and 400 mg/kgshowed signicant (p< 0.01) anti-inammatory activity in carrageenan induced acute inammation when compared to the control. EEAC was also effective in chronic arthritis model in dose-dependent manner. Conclusion:The present study indicates that EEAC has signicant anti-inammatory activity against both acute and chronic inammation.

.The main purpose of present study was to perform phytochemical screening and explore the anti-hyperglycaemic properties of Alangium salvifolium root extract in normal and alloxan induced diabetic rats. A. salvifolium root gave maximum extractive values of 6.4 % w/w with Ethanol and other parameters were within limits. The extract gave positive tests for phytosterols, triterpenes, flavonoids, carbohydrates and alkaloids. The ethanolic extract of A. salvifolium was found to be nearly as potent as tolbutamide in decreasing the blood glucose levels in normal fasting rats. In normal control group the percent reduction in blood glucose indicated that the extract is fast acting. The extract showed significant decrease in blood glucose, when compared with tolbutamide. The evaluated blood glucose levels in alloxan induced diabetic rats were significantly decreased up to 24th h compared to tolbutamide. A single oral administration of alcoholic extract at doses 100, 250 and 500 mg per kg produced a significant blood glucose reduction in a dose dependent manner in normal and diabetic rats. These data confirm the hypoglycaemic and anti-hyperglycaemic effect of alcoholic extract of A. salvifolium root in normal and diabetic rats respectively when compared with standard drug tolbutamide.Keywords: Alangium salvifolium; Ethanolic extract; Alloxan induced; Hypoglycaemic action.© 2011 JSR Publications.

Abstract Vanadium (V), a heavy metal, has been reported to induce central nervous system toxicity leading to various behavioural impairments. It is characterized by the production of reactive oxygen. The present study was designed to test the possibility of Grewia carpinifolia ethanolic extract in preventing behavioural alterations following acute vanadium toxicity in mice. Twenty five Swiss albino mice (25—27 g) were completely randomized into 5 groups (A—E) of 5 animals each. Group A received distilled water and served as a control; group B, received vitamin E (500 mg.kg−1 b. w. every 72 hours), a known antioxidant orally, along with a daily dose of sodium metavanadate intraperitoneally (i. p.) for 7 days; group C and group D received Grewia carpinifolia leaf extract at 100 and 200 mg.kg−1 b.w orally respectively, along with the sodium metavanadate i. p. for 7 days; while group E received sodium metavanadate i. p. only for 7 days. The behavioural and motor functions were analysed by the open field, negative geotaxis, and hanging wire tests; the daily body and brain weights were recorded. Grewia carpinifolia ethanolic extracts significantly reduced the number of grooming, stretched attend posture, and freezing time that were significantly increased in the vanadium only group and also enhanced the vestibular functions. In addition, the latent time spent on the hanging wire in groups simultaneously administered with the extract and V compared favourably (P > 0.05) with the control groups but a decrease in latent time was observed in the V only group. The results suggest that acute V toxicity results in various behavioural deficits and support a possible role of Grewia carpinifolia as a protective agent against acute vanadium-toxicity with a better result at 200 mg.kg−1 b. w.

Withania frutescens (W. frutescens) is a medicinal plant widely used to treat several diseases. This work aims to study phytochemical composition as well as acute and subacute toxicity of W. frutescens hydroethanolic extract in mice. The phytochemical composition of W. frutescens extract was performed using gas chromatographic analysis. Acute toxicity was studied in vivo with oral administration of single doses 400 mg/kg, 1000 mg/kg, and 2000 mg/kg for 14 days. Subacute toxicity was studied with the administration of repeated doses of 400 mg/kg/day and 2000 mg/kg/day for 28 days. Phytochemical analysis of W. frutescens hydro-ethanolic extract confirmed the presence of interesting chemical compounds. Acute toxicity results showed no toxic symptoms in mice treated with an increasing dose up to a maximum of 2000 mg/kg. Alongside acute toxicity, subacute data showed no clinical symptoms nor biochemical or histological alteration in mice treated with an increasing dose up to a maximum of 2000 mg/kg compared to the control group (p < 0.05). This study shows no toxic effects in animals treated with W. frutescens extract, and, therefore, this plant can be considered safe in animals up to 2000 mg/kg under both acute and subacute toxicity conditions.

  Objectives: Atherosclerosis was experimentally induced in New Zealand white male rabbits by cholesterol feeding for 120 days for investigating effects of 70% ethanolic Elaeocarpus ganitrus seed extract (EEGS) against atherosclerosis.Methods: Anti-atherosclerotic activity of E. ganitrus extract was evaluated at a dose level of 250 and 500 mg/kg of body weight (p.o). On 121st day, the animals were sacrificed to collect the aorta for determining tissue lipid profile, antioxidant parameters, and histopathological changes. One-way ANOVA followed by Tukey’s multiple comparison test was used for the statistical analysis.Results: Aorta of cholesterol-fed rabbits for 120 days showed marked elevation in total cholesterol, triglycerides, and phospholipids. EEGS extract treatment significantly (p≤0.01, ≤0.001) corrected disturbed lipid profile in cholesterol-fed rabbits in a dose-dependent manner during the 60 days of the treatment period. A significant reduction in lipid peroxidation and a considerable raise in glutathione, catalase, and superoxide dismutase levels (p≤0.01, ≤0.001) were accompanied by post-treatment with EEGS extract to cholesterol-fed rabbits. The histopathological modifications such as accumulation of foam cells, atheromatous plaque formation, and lumen size reduction supported the successful induction of atherosclerosis in rabbits. The treated rabbits showed significant protective effect by lowering the deposition of cholesterol and increasing the lumen size compared to cholesterol-fed group.Conclusions: Phytoconstituents such as alkaloids, tannins, flavonoids, steroids, triterpenoids, and carbohydrates in the ethanolic extract may be attributed to effective anti-atherosclerotic and antioxidant activity of plant extract. Our study exhibited that EEGS extract could be a potent herbal therapeutic agent for the treatment of atherosclerosis and hypercholesterolemia-related diseases.
