摘　　要：以金银花(Lonicera japonica Thunb)为原料,采用单因素试验研究了乙醇体积分数、微波时间、微波功率、料液比和提取次数等因素对提取金银花中黄酮类化合物的影响,得到最适提取条件为在乙醇体积分数60%、微波功率300 W、微波时间3 min、料液比1∶20(g∶mL)下提取3次。金银花中含有丰富的黄酮类化合物,具有较强的抗氧化能力,是良好的天然抗氧化剂。Taking honeysuckle as raw materials, the effects of microwave concentration, microwave power, microwave time and solid-liquid ratio were studied by single factor experiment. The results showed that the optimum technology conditions were as follows： microwave concentration 60%; microwave power 300 W; microwave time 3 min; solid-liquid ratio 1：20 and extracting for three times. It indicated that honeysuckle had abundant flavonoids and strong antioxidative activity, which was a good natural antioxidant.
