目的:对淫羊藿中淫羊藿苷的提取工艺进行优化研究。方法:以淫羊藿苷的含量为质量控制指标,通过均匀设计的方法,对淫羊藿提取工艺中乙醇体积分数、固(g)液(mL)比和超声提取时间等因素进行研究,考察淫羊藿苷的提取工艺。结果:以80%乙醇为溶剂,固液比为1∶20,超声提取时间为20min,可使药材中淫羊藿苷最大程度的浸出。结论:此工艺提取淫羊藿中有效成分淫羊藿苷的效率较高。
Objective: To optimize the extraction process of icariin in Epimedium. Methods: The content of icariin was used as the quality control index. Through the uniform design method, the ethanol volume fraction, solid (g) liquid (mL) ratio and ultrasonic extraction time were studied. The extraction process of icariin. Results: With 80% ethanol as the solvent, the solid-liquid ratio was 1:20, and the ultrasonic extraction time was 20 min, the leaching of icariin in the medicinal materials could be maximized. Conclusion: This method has high efficiency in extracting icariin, an effective component of epimedium.
