摘　　要：以连翘[Forsythiae suspentsa(Thunb.)Vahl.]为试材,采用单因素试验法,研究了乙醇体积分数、微波时间、微波功率、料液比和提取次数对连翘黄酮类化合物提取的影响及连翘黄酮类化合物的抗氧化性,确定了提取的最适工艺参数。结果表明,连翘黄酮类化合物的最适提取工艺参数为乙醇70%,微波功率250 W,微波时间5 min,料液比1∶20和提取2次。连翘黄酮类化合物具有一定的清除羟自由基的能力。Using[Forsythiae suspentsa（Thunb.）Vahl.] as material, effects of volume fraction of alcohol, microwave time, microwave power, ratio of material to solvent and extracting times on extracting were studied the total flavonoids from weeping forsythia. The antioxidative activity of total flavonoids from weeping forsythia was determined. The results showed that the optimum technology conditions were the concentration of alcohol 70%, microwave power 250 W, microwave time 5 min, ratio of material to solvent 1∶20 and extracting twice. The total flavonoids from weeping forsythia had the ability of cleaning up the hydroxyl radical.
