| 摘 要： | 用不同剂量的武夷岩茶茶多酚抑制邻苯三酚自氧化速率，测定茶多酚体外清除超氧阴离子自由基的作用，并与Vc进行比较。结果：Vc（1mg／inl）O．1rrd和0．2ml对邻苯三酚自氧化的抑制率分别达到69．91±10．82（％）和93．59±1．73（％）；0．2ml剂量的作用显著高于0．1ml（均P〈0．01）。茶多酚（1mg/ml）0．1、0．2、0．3rid对邻苯三酚自氧化的抑制率分别达到23．94±4．06（％）、34．81±3．59（％）、47．42±2.30（％），剂量增加，抑制作用也显著增加（均P〈0．01和0．05）。说明茶多酚具有显著的体外清除超氧阴离子自由基、抗氧化的作用，但其作用不及Vc。

| Abstract: | The speed of autoxidation of pyrogallol was suppressed by different doses of Wuyi rock tea-polyphenls, the article researches the removing function of tea-polyphenls superoxide anion readical, compared with Vc. The results are shown as follows：the suppression rates of 0.1ml and 0.2ml of Ve （lmg/ml）went up by 69.91±10.82 （%）and 93.59±1.73 （%）respectively,the function of 0.2ml dose was marked higher than that of 0.1ml dose （all P〈0.01 ）.The suppression rates of 0.1ml,0.2ml,0.3ml of tea-polypheuls were up to 23.94±4.06 （%） ,34.81±3.59 （%）,47.42±2.30（% ）respectively ,their results were different in dose group （all P〈0.01 and 0.05）.The results show that the tea-polyphenls have remarkable function of removing superoxide anion readieal in vitro,but weaker than that of Ve. |
