【摘要】 采用DPPH法、α-脱氧核糖氧化法(对·OH的清除能力)和普鲁士蓝法(还原能力)3种方法测定提取物抗氧化活性,比较了9种常见植物秸秆的抗氧化活性。结果显示:凤眼莲叶和法桐落叶在3种测试方法中均显示出了强抗氧化能力,而稻草和麦秆均为抗氧化能力较弱的植物。各种抗氧化能力测试方法之间存在一定的相关性。更多还原

【Abstract】 DPPH assay,α-deoxyribose oxidation assay(hydroxyl radical -scavenging) and FRAP assay(Ferric Reducing Antioxidant Power) were used to determine the antioxidant activity from the extracting material in 9 plants.The results showed that Eichhornia crassipes and Indus deciduous leaves had high antioxidant activities in all three antioxidant activity assays,while straw and stem showed low antioxidant activities.There were positive correlations between the antioxitant activity assays.更多还原
