Abstract: The antioxidant effects of polyphenol from Rodiola rosea were studied. The scavenging capacities of polyphenol of Rodiola rosea on 2,2-diphenyl-1-picrylhydrazyl and superoxide free radical were assayed. The results showed the polyphenol of Rodiola rosea has characteristics of scavenging 2,2-diphenyl-1-picrylhydrazyl, superoxide, hydroxyl free radical and definite antioxidant effects on oil.
Key words: polyphenol, Rodiola rosea, antioxidant, free radical
