摘要
确定延胡索乙素最佳提取工艺。采用超声波提取法,以延胡索乙素的吸光度为考察指标,结合单因素试验和正交试验,确定了延胡索乙素的最佳提取工艺条件。提取延胡索乙素的最佳提取工艺参数为:以体积分数为70%的乙醇为提取剂,超声功率为350 W,提取料液比为1∶20,超声时间为60 min。结果显示,所确定的最佳提取工艺稳定可行。
Objective： The extraction coditions of tetrahydropalmatine from Yanhusuo were optimized. Methods： Ultrasonic extraction methods of tetrahydropalmatine was studied by single factor test and orthogonal test, the absorbance of tetrahydropalmatine was used to evaluate the factor levels. Results： Optimum extraction conditions were determined as follows： 70% ethanol for the extraction agent, ultrasonic power 350 W, the ratio of the solid to liquid 1 ： 20, ultrasonic time 60 min. Conclusions： This extractive condition was the best way.
