The extraction technology of flavonoids in the bulb of Lilium lancifolium Thunb. was studied by comparing the ultrasonic wave extraction technology with the traditional extraction technology. The results showed that the ultrasonic method was better. Also, the optimal procedure for the ultrasonic wave method were studied. Under the conditions of 1:30 of 80% ethanol to the bulb of Lilium lancifolium Thunb. weigh ratio, ultrasonic treatment for 40 min twice at the temperature of 70 degrees C, the average extraction rate of flavonoids was as high as 99.25%.
通过将超声波提取技术与传统提取技术进行比较，对卷丹鳞茎中黄酮类化合物的提取工艺进行了研究。结果表明，超声波法效果更佳。此外，还研究了超声波法的最佳工艺。在80%乙醇与卷丹鳞茎重量比为1:30的条件下，于70℃温度下超声处理40分钟，重复两次，黄酮类化合物的平均提取率高达99.25%。
