茶多酚和槲皮素对全血吞噬细胞产生活性氧的抑制作用

The scavenging effects of tea polyphenol and quertin on oxygen free radicals in PMN system

采用化学发光法（ＣＬ）和顺磁共振法（ＥＳＲ）对比研究了茶多酚和槲皮素两种酚羟基化合物在吞噬细胞体系中清除超氧阴离子（Ｏ·２）、羟自由基（ＯＨ·）和单线态氧（１Ｏ２）等活性氧的能力，研究表明茶多酚和槲皮素在体外皆为非常有效的氧自由基清除剂，茶多酚的效果更好一些．ＣＬ法和ＥＳＲ法研究的结果具有一致性．

Using chemiluminscene(CL) and ESR spectroscopy techniques, the tea polyphenol and quertin's ability to scaveng O · 2、OH ·、 1O 2 in PMN system has been studied. The results showed that tea polyphenol and quertin are both effective free radicals scavengers. Tea polyphenol is better. The rsults of CL are consistent with ESR.
