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-·,分光光度法研究伸筋草体外清除活性氧自由基的作用。用硫代巴比妥酸(TBA)分光光度法研究伸筋草对·OH诱发卵磷脂脂质过氧化损伤的抑制作用。实验结果表明,紫堇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 corydalis 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 corydalis.on the lecithin lipid peroxidation were observed by thiobarbit uric acid spectrophotometry. The results showed that corydalis could scavenge active oxygen efficiently.
