Study on the Antioxidant Activity of the Chinese Herb Rhodiola Sachalinensis A. Bor Extract

Abstract

Abstract: Antioxidant substance of radix Rhodiolae was extracted with ethanol. Using the assay systems of hydroxyl radicaland superoxide anion radical, antioxidant activity of the extract of radix Rhodiolae was studied, and in comparison with TBHQand Vitamin E. The results showed that the extract of radix Rhodiolae had good antioxidant activity in different assay systemsand scavenging effects on superoxide anion radical was stronger than hydroxyl radical. The result was better than Vitamin E.

Key words: Radix Rhodiolae, hydroxyl radical, superoxide anion radical, antioxidant activity
