Evaluation of Antioxidant and Antidiabetic Activities of Extracts.

Oxidative stress plays a major role in diabetic physiopathology; hence, the interest of using natural antioxidants as therapeutic tools exists. The aim of this study was the evaluation of antioxidant activity and inhibitory potential of organic extracts from roots against key enzymes linked to hyperglycemia. Antioxidant activity was performed using 2,2'-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radicals and ferric reducing/antioxidant power (FRAP) methods.
