目的：优选三七药粉醇回流法提取与醇超声法提取最优工艺参数;探讨三七药粉超声提取的可行性,为工业化生产提供依据。方法：以三七皂苷R_1、人参皂苷Rg_1、人参皂苷Rb_1及三种皂苷总和的含量为评价指标,首先采用正交设计试验法筛选三七药粉醇超声提取与醇回流提取各自的最优工艺条件,再用配对t检验法对比分析试验数据。结果：三七醇超声提取最优工艺参数为：三七药材超微粉加入30%的乙醇浸泡30 min,30%乙醇体积为药材量的6倍,超声时间30 min。三七醇回流提取最优工艺参数为：三七药材超微粉加入50%的乙醇浸泡30 min,50%乙醇体积为药材量的10倍,水浴回流时间30 min。三七药粉醇回流与超声提取差别...

To optimize the extraction process of alcohol refluxing method and ultrasonic method for pseudo-ginseng powders and investigate the feasibility of ultrasonic extraction to provide the basis for the industrial production.Method：The content of iiotoginsenoside R,,ginsenoside Rg,and Rb,,and the total content of the three saponins as the indices,the technique parameters of reflux and ultrasonic extraction process for pseudo-ginseng were optimized with orthogonal design,and the experimental data were analyzed using paired samples test.Result：The o...
