| 摘 要： | 采用α-脱氧核糖法、邻苯三酚自氧化法、DPPH法、铁氰化钾还原法等4种国内外常用的体外抗氧化活性检测方法,对鄂西北产鱼腥草石油醚提取物、无水乙醇提取物、乙酸乙酯提取物、三氯甲烷提取物的抗氧化性进行化学评价,结果表明鱼腥草提取物具有一定抗氧化性,其浓度与其抗氧化活性强弱顺序一致。

| Abstract: | In this paper,the in vitro antioxidant activity of extracts Houttuynia cordata from northwestern Hubei which were respectively extracted by petroleum ether,ethanol,ethyl acetate and chloroform,were evaluated by the α-deoxyribose method,pyrogallol autoxidation method,DPPH method and potassium ferricyanide reduction method.The results showed that all the extracts of H.cordata had some antioxidant activities,and positive correlations were found between its antioxidant activities and its concentration. |
