摘　　要：采用微波法对黄花菜中黄酮类化合物进行提取,并采用分光光度法对提取率进行测定。实验确定了最佳提取条件:乙醇质量分数50%,溶剂倍数20倍,微波功率150 W,提取时间4 min。此条件下黄酮类化合物的平均提取率为3.756%,平均回收率为99.12%,RSD为2.135%(n=5)。微波法提取黄酮类化合物提取率较高、所需时间较短,是一种快速节能的提取工艺。To determine the optimum extract process of flavonoids in hemerocallia fulva,the microwave extraction method and spectrophotometry were adopted in the experiment.The optimum process is that the ethanol concentration is 50%,solvent is 20 times as medicinal material,the microwave time is 4 min and microwave power is 150 W.The results show that flavonoids in hemerocallia fulva is 3.756%,the average recovery is 99.12% and the relative standard deviation is 2.135%（n=5）.The microwave extraction could obtain the high content of flavonoids and the experiment time is short.
