摘要
提取八种中药材有效成分,采用邻苯三酚自氧化法测定抗氧防衰性能,检测波长为319nm,时间5min,邻苯三酚浓度为4.5mM,缓冲液pH为8.2,以IC500值作为评价指标。实验结果表明:不同中药材具有不同抗氧能力。且均成量效关系,抗氧能力为山楂〉菊花〉银杏叶〉甘草〉当归〉枸杞〉何首乌〉红景天。
The effective component of eight Chinese herbs are extracted and pyrogallol autoxidation is adopted to determine the anfioxidant failure performance of these herbs. Detection wavelength is 319 nm,fime 5min,pyrogallol concentration 4.5 mM and buffer pH 8.2, with IC50value concentration as the evaluation index. Experimental results show that different Chinese herbs have different antioxidant ability with dose-effect relationship. Their antioxidant order is as follows: hawthorn 〉chrysanthemum〉 ginkgo biloba 〉 licorice〉 angelica〉woltberry〉 fleece-flower root〉 rhediola.
