摘　　要：目的:优选淫羊藿中淫羊藿苷的提取工艺。方法:以淫羊藿苷提取转移率为考察指标,对不同提取方法和提取条件进行考察。结果:最佳提取工艺为采用渗漉法,用60%～75%乙醇作溶媒,收集渗漉液的量为药材的8倍。此时,淫羊藿苷提取转移率为90%。结论:该提取工艺效率高、节约能源,方法可行。OBJECTIVE： To optimize the extraction technology of icariin from Herba Epimedii. METHODS： With the extraction transfer rate of icariin as index, the different extraction methods and extraction conditions were investigated. RESULTS： The percolation method was confirmed to be the optimal extraction technology in which 60%-75% alcohol was used as solvent and the amount of the collected percolate was 8 times that of the medicinal material. Under the above condition, the extraction transfer rate of icariin was as high as 90%. CONCLUSION： The extraction technology is highly efficient, re- source- saving and practicable.
