Antihyperglycemic and antihyperlipidemic effects of Tephrosia purpurea leaf extract in streptozotocin induced diabetic rats.

Diabetes mellitus is a worldwide leading metabolic syndrome, associated with profound alterations in carbohydrate, lipids, lipoproteins and protein metabolisms. Worldwide, traditional practitioners for the treatment of diabetes and its complications use a wide variety of medicinal plants. In the present study the aqueous extract of Tephrosia purpurea leaves (TpALet) was evaluated for its antihyperglycemic and antihyperlipidemic effects in streptozotocin induced diabetic rats.

Effects of Tephrosia purpurea aqueous seed extract on blood glucose and antioxidant enzyme activities in streptozotocin induced diabetic rats.

The aim of the present study was to evaluate the effects of aqueous seed extract of Tephrosia purpurea (TpASet) on blood glucose and antioxidant status in streptozotocin induced diabetic rats. Hyperglycemia associated with an altered hexokinase and glucose-6-phosphatase activities, elevated lipid peroxidation, disturbed enzymatic [Superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx)] and non enzymatic [Glutathione, vitamin C and vitamin E] antioxidant status were observed in streptozotocin induced diabetic rats. Oral administration of "TpASet" at a dose of 600 mg/kg body weight showed significant improvement in above mentioned parameters.

Antihyperglycemic and antilipidperoxidative effects ofTephrosia purpurea seed extract in streptozotocin induced diabetic rats.

The aim of the present study was to evaluate the antihyperglycemic and antilipidperoxidative effects of ethanolic seed extract ofTephrosia purpurea (TpEt) in streptozotocin induced diabetic rats. Hyperglycemia associated with an altered hexokinase and glucose 6 phosphatase activities, elevated lipid peroxidation, disturbed enzymatic and non-enzymatic antioxidants status were observed in streptozotocin induced diabetic rats. Oral administration of "TpEt" at a dose of 300mg/kg bw showed significant antihyperglcemic and antilipidperoxidative effects as well as increased the activities of enzymatic antioxidants and levels of non enzymatic antioxidants.
