Antidiabetic and hypolipidemic activities of Kigelia pinnata flowers extract in streptozotocin induced diabetic rats

Objective

To evaluate antidiabetic and hypolipidemic activities of Kigelia pinnata methanolic flowers extract in streptozotocin (STZ) induced diabetic wistar rat.

Methods

Rats were made diabetic by a single dose of STZ at 60 mg/kg body weight i.p. The blood glucose level was checked before and 72 h after STZ injection to confirm the development of diabetes. The flower extract and glibenclamide were administered orally at the doses of 250 and 500 mg/kg body weight for 21 days.

Results

Daily oral treatment with the extract and standard drug for 21 days significantly reduced blood glucose, serum cholesterol and triglycerides levels. High density lipoprotein-cholesterol level was found to be improved (P<0.01) as compared to diabetic control group.

Conclusions

It is concluded that Kigellia pinnata flowers extract have significant antidiabetic and hypolipidemic effect.
