In this work, the antioxidant activities of kaempferitrin, afzelin, rhamnoisorobin and kaemferol, which are themain flavonols of Hibiscus cannabinus L were studied. Kaempferol, aglycone of kaempferitrin, was found tobe the most effective antioxidant and the antioxidant activity was decreased in the order of rhamnoisorobin,afzelin and kaempferitrin. The difference of DPPH radical scavenging activity between kaempferol andkaempferitrin was as high as 26.6 times. Although they have the same main structure except that they havetwo rhamnose (kaempferitrin) or one rhamnose (rhamnoisorobin, afzelin) or no rhamnose (kaemperol), theantioxidant activities of them were very different. The cause of this difference is not yet clear, but it seemsthat the rhamnose in the flavonol plays a critical role to determine the antioxidant activity of flavonols. Fromthis result, we could conclude that the flavonoids with glycoside extracted from many kinds of plants shouldbe converted into aglycones before they are employed as the antioxidant ingredient of cosmetics.
