The aqueous extract of Clitoria ternatea Linn leaves were screened for its antihyperglycemic activity in streptozotocin induced and glucose induced diabetic rats in doses of 100, 250 and 500 mg/kg body weight.At a dose of 100 mg/kg (bw), aqueous leaf extract did not produce significant antihyperglycemic activity, however a doses of 250 mg/kg of Clitoria Ternatea leaf extracts significantly reduced the glucose levels in the blood as compared to the standard drug, chlorpropamide at the end of 2 hrs. Increase of the dose does not show any significant increase in the activity. Aqueous leaf extract of Clitoria Ternatea significantly reduced (p<0.001) the elevation of glucose in the glucose-induced diabetic rats at 1 hr. From the results, it is concluded that the acute dose of aqueous extract of Clitoria ternatea Linn leaves exhibits good antihyperglycemic activity.
