Antihyperglycemic and hypolipidemic activities of aqueous extract of Carica papaya Linn. leaves in alloxan-induced diabetic rats

Abstract

Background:India is considered as the diabetic capital of the world. The study of plants having antihyperglycemic and hypolipidemic activities may give a new approach in the treatment of diabetes mellitus.Objective:The study was intended to evaluate the antihyperglycemic and hypolipidemic activity of aqueous extract of leaves of Carica papaya Linn. (AECPL) in alloxan-induced diabetic albino rats.Materials and Methods:Diabetes was induced in albino rats by administration of alloxan monohydrate (120 mg/kg, i.p.). Rats were divided into 6 groups of 6 animals each. First group served as non-diabetic control, second group as diabetic control, third group as standard and was treated with 0.1 mg/kg/day of glibenclamide. Group 4, 5, and 6 received 100, 200, and 400 mg/kg body weight of AECPL. Blood samples were analyzed for blood glucose on day 0, 1, 7, 14, 21 and lipid profile on day 21.Results:The AECPL showed significant reduction (P<0.01) in blood glucose level and serum lipid profile levels with 400 mg/kg body weight in alloxan-induced diabetic rats as compared with the control.Conclusion:It is concluded that AECPL is effective in controlling blood glucose levels and in improving lipid profile in diabetic rats.
