ABSTRACT

The ethanolic leaves extracts of Hymenocardia acida was screened for anti-diabetic activity based on folklore and little or no work cited in literature. Hymenocardia acida (Family: Hymenocardiaceae) has a very high anti-diabetic potentials which appeared comparable to the control glibenclamide in alloxan induced diabetes mellitus. The study evaluated the ethanolic leaves extract of H. acida for anti-diabetic activity in a rat model of non-insulin dependent diabetes mellitus (NIDDM). In a dose-response study over a six-hour period, 500 mg/kg oral dose of the extract gave the best anti-diabetic activity and was therefore employed in the study. Since daily oral administration of the ethanolic extract of H. acida reduced the raised blood glucose levels observed during the 14 days studies. The extract did not demonstrate any acutely toxic effect in rats within the dose range (250 mg/kg - 5000 mg/kg) employed in the study; hence it was well tolerated by the rats. In all experiments, the effect was dose-dependent and comparable to that of glibenclamide (2 mg/kg), an oral sulfonylurea standard used in the experiments.
