摘　　要：研究槲皮苷及其苷元槲皮素对羟基自由基、超氧阴离子自由基和二苯代苦味肼基(DPPH)自由基的清除作用。实验结果表明,槲皮苷和槲皮素对羟基自由基、超氧阴离子自由基及DPPH自由基有不同程度的清除作用,且清除DPPH自由基的能力最强,同时表现出明显的量效关系。To study the effects of quercitrin and quercetin on hydroxyl radical scavenging activity, superoxide anion radical scavenging activityand DPPH radical scavenging activity. The results showed that quercitrin and quercetin exhibited a radical scavenging activity against hydroxylradical,superoxide anion radical and DPPH radical,and that scavenging activity against DPPH radical was the strongest of all. There exists anobvious dose- response relationship.
