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O.-2,分光光度法研究了广枣提取物体外清除活性氧自由基的作用。用硫代巴比妥酸(TBA)分光光度法研究广枣提取物对.OH诱发卵磷脂脂质过氧化损伤的抑制作用。实验结果表明,广枣提取物能有效清除活性氧自由基,对卵磷脂脂质过氧损伤有显著抑制作用。Scavenging effects of Choerospondia on active oxygen species · OH and O2^- generated by Fenton reaction and riboflavine photosensitization in vitro were investigated by the means of spectrophotometry. The inhibition effects of Choerospondia on the lecithin lipid peroxidation induced by hydroxyl radical were observed by thiobarbit uric acid spectrophotometry. The results showed that Choerospondia could scavenge active oxygen efficiently. It could also significantly inhibitlipid peroxidation by hydroxyl radical.
