摘　　要：考察北五味子乙醇提取物及其各萃取组分(二氯甲烷、乙酸乙酯、正丁醇、水)对DPPH自由基的清除能力.试验结果表明,随着五味子浓度的增加,五味子提取物及其各组分对DPPH自由基的清除能力有着不同的量效关系,其中乙酸乙酯组分对DPPH自由基清除能力最强,该结果可为五味子抗氧化作用的研究提供参考.The DPPH radical scavenging capacity of the Schisandra chinensis ethanol extracts and four extract components（ dichloromethane,ethylacetate,butanol,water） were investigated. The experimental results showed that with the increase of concentration,Schisandrae chinensis extracts and the scavenging ability of DPPH free radical had a different dose effect relationship,and the ethyl acetate part had the strongest scavenging ability on DPPH radical.This result could provide a reference for the ability of Schisandra antioxidant effect.
