| 摘 要： | 以甲基紫作为反应物检测了多种化合物对Fenton反应产生羟自由基的清除作用.结果表明各化合物清除羟自由基的能力都与浓度呈依赖关系.以清除率大小表示其抗氧化作用,其由强到弱的次序为:芦丁,茜素红,HBT＞VE,槲皮素＞迷迭香酸＞香草醛,阿魏酸＞Trolox＞葛根素,焦性没食子酸,芹菜素＞硫脲,茴香醛,亚硒酸钠＞VC,香豆素＞甘露醇.

| Abstract: | The methyl violet assay was employed to detect the OH scavenging activities of several chemicals and the results showed that all the chemical activities were concentration dependent and their abilities to scavenge the hydroxyl free radical were in the descending sequence of rutin,alizarin red,HBT>VE, quercetin>rosmarinic acid>vanillin,ferulic Acid>Trolox>puarerin,pyrogallic acid,apigenin>thiourea,anisaldehyde, sodium selenite>VC,coumarin>mannitol. |
