摘　　要：目的研究淫羊藿中淫羊藿苷的提取工艺条件。方法采用HPLC法对不同提取工艺条件下淫羊藿苷含量进行测定,探讨不同提取溶媒、煎煮时间、浓缩时间及温度、药材粉碎度对淫羊藿苷含量的影响。结果不同提取方法对淫羊藿中淫羊藿苷的提取率影响较大。结论本研究可为工业大生产中合理地提取淫羊藿活性成分提供参考。Objective To optimize the extraction process for icariin from Herba Epimedii. Methods The content of icariin in the extracts obtained by different extraction methods was determined with HPLC. The effect of solvents, boiling time, extracting time and temperature, and the size of the medicinal powder was observed. Results Different extraction methods had great influence on the extraction rate of icariin. Conclusion This research can provide evidence for the extraction of active component from Herba Epimedii in industrial production.
