摘要: 本文选用FRAP(FerricReducingAntioxidantPowder)法、DPPH(1,1-Diphenyl-2-picryl-hydrazyl)法和β-胡萝卜素亚油酸体系三种体外抗氧化测定方法,以Trolox(6-Hydroxy-2,5,7,8-tetramethyl-2-carboxylicacid)为阳性对照物,以水和80%乙醇作为样品提取剂,对30种植物样品的抗氧化活性进行综合比较分析。结果显示,五倍子的抗氧化性最强。

Abstract: In this article, three in vitro measuring methods were used, including FRAP, DPPH and the bleaching of β-carotene- sub-oleic acid method, so as to study the antixidative activities of 30 plants samples comprehensively. H2O and 80% ethanol were considered as the extracting agents of the plants while the trolox as the positive control. The results showed that the antixidative activity of Chinese gall is the strongest.
