| 摘 要： | 采用电子自旋共振法(ESR)、光敏化合物微生物法、光度法对白花丹提取物的抗氧化性能进行了检测.结果:白花丹提取物对单线态氧自由基、混合自由基、羟自由基及香烟烟气自由基的清除率分别是53.3%、59.1%、40.2%、26.0.0%,白花丹提取物具有较好的抗氧化性能,其抗氧化能力与其质量浓度呈正相关.

| Abstract: | Test is made to antioxidation activity of extracts of Plumbago Zeyanica L.by ESR method,photosensitized compound microbiological method and photometric method.The result shows that the removing percentages to ~(1)O_(2) free radical,mixed-oxygen free radical,hydroxy radical and free radical of solid in cigarette smoke are 53.3%,59.1%,40.2%,26.0% respectively.So it has fine antioxidation activity.The capability of antioxidation is directly proportional to the concertration. |
