ABSTRACT
Objective: The present study was conducted to evaluate the antihyperglycemic activity on chronic administration of the butanol fraction of the ethanol extract of Moringa Stenopetala leaves in alloxan induced diabetic mice. Methods: The mice were grouped in four groups; Normal control, Diabetic control, Butanol fraction treated and standard drug treated groups. The Diabetic mice received the butanol fraction of Moringa stenopetala daily for 28 days. Results: The butanol fraction of Moringastenopetala treatment resulted in significant reduction of fasting blood glucose level, serum total cholesterol and triglycerides level. This fraction also showed a tendency to improve body weight gain in diabetic mice. Its oral LD50 was found to be greater than 5000mg/Kg indicating its safety in mice. Conclusions: Though the mechanism of action of Moringa stenopetala seems to be similar to that of sulfonylureas, further studies should be done to confirm its mechanism of antidiabetic action. Furthermore the active principle(s) responsible for the antidabetic effects should also be identified.
