Abstract

Abstract: To evaluate the antioxidant potential of secoisolariciresinol diglusoside (SDG), the abilities of SDG to scavenge DPPH and superoxide anion radicals and hydrogen peroxide, and its reducing power were assayed. Results showed that SDG had excellent antioxidant effect. Its reducing power was positively linearly correlated with concentration. SDG at 150 μg/mL could scavenge half of DPPH free radicals and more. A superoxide anion radical scavenging rate of 55.81% was observed for SDG 0.3μg/mL. The hydrogen peroxide scavenging capacity of SDG initially increased to a maximum of 86.87% at 150 μg/mL and then decreased as its concentration increased.

Key words: secoisolariciresinol diglusoside (SDG), antioxidant activity, free radical
