EXPERIMENTAL VALIDATION OF ANTI-DIABETIC AND ANTIOXIDANT POTENTIAL OF T. CORDIFOLIA STEMS (M.): AN INDIGENOUS MEDICINAL PLANT

This case control study had been carried out to evaluate antidiabetic and antioxidant activities of Tinospora cordifolia (T. cordifolia; family: Menispermaceae) against streptozotocin induced diabetes in experimental rats to scientifically validate its use against diabetes. Ethanolic extract of T. cordifolia stem extract and standard drug (glibenclamide) macerated with aqueous gum acacia (2%, w/v) suspension and fed orally to streptozotocin induced male adult diabetic rats of Charles Foster strain for 30 days. Biochemical parameters in normal, diabetic control, standard (600μg/kg bw p.o.) and treated (500 mg/kg bw p.o.) animals group were determined and compared. Treatment of streptozotocin induced diabetic rats with ethanolic extract caused significant (p<0.001) reduction in blood glucose, total cholesterol, triglyceride, phospholipids, free fatty acid, lipid peroxide and significant increased (p<0.001) post heparin lipolytic activity. Furthermore, the stem extract (100-400 μg) when tested for its antioxidant activity in vitro, shown significant (p<0.001) inhibit the generation of super oxide anions in enzymic system a, in enzymic system b, non enzymic system and hydroxyl radicals in enzymic system and non-enzymic system. The results of the present study demonstrated antidiabetic antidyslipidemic and anti oxidant activities of T. cordifolia stem extract which could help in prevention of diabetic- dyslipidemia and related complications.
