摘要: 根据Fenton和Haber-Weiss反应,以脱氧核糖作为羟自由基分子探针,检测脱氧核糖降解物与硫代巴比妥酸显色反应,对照分析超氧歧化酶(SOD)、茶多酚、硫脲、人参对含氧自由基的清除作用,证明茶多酚能抑制氧化物阴离子自由基(O一2),作用与SOD相似。
关键词: 茶多酚, 人参, 自由基
Abstract: Based on reaction of Fenton and Haber - Weiss,by using the deoxyribose as a hydroxy radical moleculor,probe the degradation product of deoxyribose by thiobarbituric acid reaction was tested,and compared .The action and potency of scavenging oxygen radical species by superoxide dismutase(SOD),thiourea,tea- polyphenol and ginseng were studied.The results showed that tea- polyphenol could inhibit the anion radical action of superoxide(O2- ) with the effect similar to that of SOD. However ginseng could inhibit not only hydroxyradical(OH) but also O2- with the effect was similar to that of thiourea.
Key words: Ginseng/pharm Polyphenol/pharm Tea/pharm Radical Scavenger
