摘 要:本文对超声波方法和传统方法提取卷丹鳞茎中总黄酮进行试验比较,同时对影响超声波提取卷丹鳞茎中总黄酮的多个因素进行正交实验分析。结果表明:超声提取总黄酮效果较好;超声波法提取的最佳方法条件为:80%乙醇,料液比1∶30,在80℃下提取40 min,连续提取2次,黄酮的总提取率可达到99.25%。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℃, the average extraction rate of flavonoids was as high as 99. 25%.
