摘　　要：利用Fenton反应产生羟自由基.OH、光照核黄素产生超氧阴离子自由基O2-.,硫代巴比妥酸(TBA)分光光度法首次对傣药纹尚海提取物体外抗氧化作用进行研究.实验结果表明纹尚海提取物能有效清除活性氧自由基,对DNA氧化损伤有显著抑制作用.Scavenging effects of Arundina graminifolia on active oxygen species ·OH and O2^-· generated by Fenton reaction and riboflavine photosensitization were investigated by themeans of spectrophotometry for the first time. The damage of DNA chain induced by hydroxyl radical were observed by thiobarbit uric acid spectrophotometry. The results suggested thatArundina graminifolia showed significant scavenging and antioxidant ability.
