Abstract

The hypoglycemic effect of ethanol extract and fractions of Nauclea latifolium leaf was evaluated in this study. The result in normoglycemic rats showed maxima glycemic reduction of 26.4% within 4 hours in the group treated with butanol fraction (250 mg/kg) which proved efficacious than glibenclamide at p < 0.05. Also, similar advantage over glibenclamide was recorded in ethanol extract (250 mg/kg) given alloxan-induced diabetic rats with % glycemic change of 44.4% as compared to 32.2% of glibenclamide within 4 hours n-hexane fraction (100 mg/kg) and butanol fraction (250/kg) recorded maxima % glycemic changes of 73.2% and 71.2%, respectively, within a period of 14 days at p < 0.05 in alloxan-induced diabetic rats. These findings suggest that ethanol extract and fractions of Nauclea latifolium leaves possess hypoglycemic.
