摘　　要：研究诃子多酚体外抗氧化活性.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,分光光度法研究了诃子体外清除活性氧自由基的作用.用硫代巴比妥酸(TBA)分光光度法研究诃子对.OH诱发卵磷脂脂质过氧化损伤的抑制作用.表明诃子多酚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.The paper studies the antioxidation in vitro of myrobalam polyphenols. Scavenging effects of my-robalam on active oxygen species ·OH and generated by Fenton reaction and riboflavine photosensitization in vitro have been investigated by means of spectrophotometry. The inhibition effects of myrobalam on the lecithin lipid peroxidation have been observed by thiobarbit uric acid spectrophotometry. The results have showed that myrobalam could scavenge active oxygen efficiently. It could also significantly inhibit lipid peroxidation and oxidation damage of DNA by hydroxyl radical.
