Antihyperglycemic and hypolipidemic effects of Hibiscus schizopetalus (Mast) Hook in alloxan-induced diabetic rats.

The antihyperglycemic and hypolipidemic activities of Hibiscus schizopetalus (Mast) Hook (Malvaceae) flower and leaves extracts were investigated in alloxan-induced diabetic rats. The hypoglycemic activity of both the extracts (100mg/kg, body weight) was tested in fasting normal rat, glucose loaded rats. Observation on body weight was also recorded. The extracts showed a significant (p<0.001) reduction in blood glucose level in normal fasting rats. In glucose tolerance test, significant (p<0.01) decreased observed in all glucose loaded animals. While in alloxan induced diabetic rats, the percent blood glucose reduction was 59.94% and 45.14% in extracts treated groups. The results obtained were compared with the reference standard drug Tolbutamide (100mg/kg, body weight). The diabetic rats showed sign of decreased in their body weight during the treatment period. Cholesterol and triglycerides levels were significantly decreased (p<0.001) by HFE. The results obtained demonstrated the potential hypoglycemic activity of methanolic extracts of H. schizopetalus. There is need of bioassay-directed assay of the active principles responsible for the anti-diabetic activity. The methanolic extracts showed the presence of carbohydrates, alkaloids, steroids, terpenes, saponins and glycosides.
