石蒜富含重要药用成分加兰他敏,为了优化石蒜中加兰他敏的微波提取工艺,以石蒜为原料、乙醇作提取剂,研究微波功率、料液比、温度、提取时间及次数等单个因素对微波法提取加兰他敏的影响,用正交实验L9（34）确定最佳工艺条件,并与超声波法进行比较。结果显示：用微波法提取石蒜中加兰他敏的最佳条件为料液比1：7,提取温度45℃,微波功率350 W,提取时间7 min;在提取2次的情况下,加兰他敏的提取率达95.8%,产率达0.0549%,粗提取物中加兰他敏含量达15.15%。用微波法提取石蒜中加兰他敏具有提取温度低、时间短、提取率高等优点,整体效果优于超声波法。

Lycoms has abundant galanthamine which is an important medical constituent. To optimize the microwave extraction technique of galanthamine in Lycoris, influences of single factors including the microwave watt, solid-liquid ratio, temperature, extraction time and times were studied using Lycorls as material and ethanol as extractant. The optimal microwave extraction condition was identified with orthogonal test L（34）, and compared with the ultrasonic method. Results showed that the best extraction condition was as follows： the ratio of sample...
