【摘要】 为探寻超声辅助提取水飞蓟素的最佳工艺条件，分别考察了提取溶剂、提取时间、提取温度、料液比对水飞蓟素提取率的影响，确定了最佳提取条件为:以无水乙醇为溶剂，时间1.5 h，温度65℃，药材和有机溶剂比为1∶14 g/m L，得到的水飞蓟素含量为35.11 mg/g。研究表明，该制备工艺合理，稳定可行，可用于水飞蓟素的提取。更多还原

【Abstract】 In order to explore the optimal technological condition of ultrasonic-assisted extraction of silymarin,the study analyzes the influencing of extraction solvent,extraction time,extraction temperature,feed liquid on the extraction efficiency of silymarin; and determines the optimal extraction condition is as follows,i. e. absolute ethyl alcohol is as solvent in 1. 5 h and under 65℃,the ratio of medicinal materials on organic solvent is 1 ∶ 14 g/m L,and silymarin is35. 11 mg/g. The study shows that the preparation technology is rational and stable,so it can be used to extract silymarin.更多还原
