目的:建立彝药毛子草中车前醚苷的提取工艺。方法:以一定浓度的乙醇为溶剂回流提取,采用正交试验法和高效液相色谱法优化提取工艺和检测方法。结果:提取工艺确定为25倍量75%乙醇,回流提取2次,每次1 h。结论:提取工艺简单,快速,成本相对较低,提取率高。
Objective: To establish the extraction process of psyllium glycosides from the root of Yi medicine. Methods: A certain concentration of ethanol as the solvent was extracted by reflux, and the orthogonal test and HPLC were used to optimize the extraction process and detection method. Results: The extraction process was determined to be 25 times the amount of 75% ethanol, reflux extraction 2 times, each 1 h. Conclusion: The extraction process is simple and rapid, the cost is relatively low, and the extraction rate is high.
