RESUMO

Objective: To evaluate the in-vivo antioxidant potential of ethanolic extract of Mentha Pulegium against CCl4 induced toxicity in rats. Methods: Animals were treated with plant extract for 7 days and then toxicity was induced with a single CCl4 intraperitoneal injection. Pre-treatment with 600 mg/kg (p.o.) of ethanolic extract of Mentha Pulegium improved the glutathione, SOD, catalase, and peroxidase levels significantly as compared to control group. Results: The present studies revealed that Mentha Pulegium has significant in-vivo antioxidant activity and can be used to protect tissue from oxidative stress. The result showed that the activities of glutathione, SOD, catalase and peroxidase in group treated with CCl4 declined significantly than that of normal group. Conclusion: Ethanolic extract of Mentha Pulegium in the dose of 600 mg/kg, p.o., has improved the glutathione, SOD, catalase, and peroxidase levels significantly, which were comparable with Liv 52. Based on this study we conclude that Ethanolic extract of MenthaPulegium possesses in vivo antioxidant activity and can be employed in protecting tissue from oxidative stress.

RESUMO

Objective: Anti-fertility activity of ethanolic extract of Jatropha gossypifolia leaf in female albino mice. Methods: Jatropha gossypifolia leaf extract, when administered orally, altered the estrous cycle pattern in female mice, prolong the length of estrous cycle with significant increase in the duration of diestrus stage and reduced significantly the number of litters in albino mice. Treatment of mice with extract of 250 and 450 mg/kg body weight/day for 21 days caused a prolonged estrous cycle with significant increase in the duration of diestrus phase and elongation of estrus stage in treatment with higher dose (450 mg/kg body weight/day). Results: The analysis of the principal hormones involved in estrous cycle regulation showed that the plant extracts altered gonadrotrophin release (LH, FSH and prolactinn) and estradiol secretion. Conclusions:The results indicated the anti-fertility effect of Jatropha gossypifolia leaf extract in female albino mice.
