摘　　要：在Co^2+-H2O产生羟自由基的稳定体系中，以溴邻苯三酚红为显色剂，用分光光度法测定吸光度的变化值，研究百合提取液在此体系中消除羟自由基的作用，通过常见抗氧化剂对羟自由基消除的量效关系，判断方法的可行性。对照实验表明，百合提取液对羟自由基有较好的消除效果。In the stable system Co 2+-H_2O_2 which can produce hydroxyl radical,bromopyrogallol red is added to determine the absorbance change by spectrophotometry. The scavenging effect of lilium extraction on hydroxyl radical is also studied. By comparing the scavenging effect of lilium extraction with that of ordinary antioxidants,the effect of this method is concluded.The result shows that lilium extraction has a good scavenging effect on hydroxyl radical.
