本文用化学发光（CL）、顺磁共振（ESR）及脉冲辐解（PR）三种方法，研究了茶多酚和檞皮素的消除,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650427&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650435&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650433&type=,和OH,•,的能力。结果表明：茶多酚和檞皮素都能有效地清除自由基，茶多酚的效果较好。三种方法所得的结果，完全一致。

Abstract

The abilities of scavenging active oxygen species,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650436&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650438&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650437&type=, and OH,·, by tea polyphenols and quercetin have been studied by chemiluminescene, ESR and pulse radiolysis. Tea polyphenols and quercetin are all phenolic antioxidants. The synergetic studies show that both tea polyphenols and quercetin are strong free radical scavengers. Tea polyphenols are better than quercetin. The results from CL studies are in good accord with those from ESR and PR studies.
