Antidiabetic and Antihyperlipidemic Activities of Methanolic Extract of Leaves of Coccinia grandis in Diabetic Rats

Coccinia grandis is a one of the edible plant and its antidiabetic and antihyperlipidemic activities are not well explored. Hence, the present is planned to study the antidiabetic and antihyperlipidemic activities of methanolic extract of Coccinia grandis leaves in streptozotocin-induced diabetic rats. Coccinia grandis leaves was dried under the shade and extracted with methanol. Preliminary phytochemical and pharmacological analysis were conducted using methanolic extract of Coccinia grandis (MECG) leaves. Female Sprague dawley (SD) was used for acute toxicity studies. Female SD was induced with diabetes by administering streptozotocin (55 mg/kg, i.p.). Glibenclamide (20 mg/kg, p.o.) or MECG leaves (125, 250 and 500 mg/kg, p.o.) used to treat diabetic rats for 28 days. Blood samples were collected at regular intervals to check the antidiabetic effect of MECG. On 28th day, blood sample was collected from the rats to analyse biochemical and lipid profile. MECG did not show any toxic symptoms up to the dose 2000 mg/kg/ BW. MECG at 125, 250 and 500 mg/kg marked significant antidiabetic and antihyperlipidemic activities. Coccinia grandis reduced streptozotocin-induced weight loss and significantly recovered lipid levels. At the end of the study, MECG exhibited significant antidiabetic and antihyperlipidemic activities in streptozotocin-induced diabetes in rats.
