目的探讨延胡索药粉超声波提取的可行性，为工业化生产提供依据。方法以延胡索乙素为评价指标，首 先采用正交设计试验法筛选延胡索药粉超声波提取与醇回流提取各自的最优工艺条件，再用配对t检验法分析实验数据。结 果延胡索醇超声提取最优工艺参数为：延胡索药粉加人50%乙醇浸泡30 min,50%乙醇体积为药材量的6倍，超声时间1.0h。延胡索醇回流提取最优工艺参数为：延胡索药粉加入50%乙醇浸泡30 min,50%乙醇体积为药材量的10倍，水浴回流时间1.0 h。延胡索药粉醇回流与超声提取差别有统计意义，回流提取优于超声提取。结论延胡索采用回流提取为佳，按最 优工艺条件提取，延胡索乙素含量最高。

Objective To probe the feasibility of ultrasonic extraction of rhizoma corydalis. Methods Using tetrahydropalmatine as the index, the optimum parameters of reflux and ultrasonic extraction process of rhizoma co-rydalis were selected with an orthogonal design. The experimental data were compared using paired sample t -test. Results The optimum technique parameters of ultrasonic extraction process were to put 50% ethanol in rhizoma co-rydalis powder and soakit 30 min. 50% ethanol was 6 times the amount of medicinal materials,the ultrasound time was 1 h. The optimum technique parameters of reflux...
