Evaluation of in-vitro and in-vivo antidiabetic, antilipidemic and antioxidant potentials of aqueous root extract of Strophanthus hispidus DC (Apocynaceae).

Background Antidiabetic activity of aqueous root extract of Strophanthus hispidus (SHP) was evaluated based on its folklore used in traditional medicine for the treatment of diabetes. Objectives: This study aimed to investigate the in-vitro and in-vivo antidiabetic potential of the aqueous root extract of SHP. Methods SHP (50, 100 and 200 mg/kg p.

Glucose utilization and anti-oxidative mechanisms of the aqueous hunteria umbellata seed extract in alloxan-induced diabetic rats.

In South-west Nigeria, water decoctions of Hunteria umbellata seeds are highly valued by traditional healers in the local management of diabetes mellitus, obesity and hyperlipidemia. Previous studies hypothesized one of the antihyperglycemic mechanisms of the aqueous seed extract of Hunteria umbellata (HU) to be mediated probably via increased peripheral glucose utilization. The present study, therefore, was designed at evaluating the peripheral glucose utilization and anti-oxidative mechanisms of 50 mg/kg, 100 mg/kg and 200 mg/kg of HU in alloxan-induced diabetic rats in Groups IV-VI rats as well as in the control groups (Groups I-III).
