摘　　要：目的:优选微波辅助提取淫羊藿中淫羊藿苷的工艺。方法:设计L(34)正交试验,以辐射温度、辐射时间、乙醇浓度、料液9比倍数为考察因素,以淫羊藿苷含量为考察指标,优选微波辅助提取淫羊藿中淫羊藿苷的工艺。结果:淫羊藿苷的最佳提取工艺为辐射温度60℃、提取时间6min、乙醇浓度30%和料液比1∶20。结论:用本方法提取淫羊藿苷,效率高、时间短、成本低。OBJECTIVE： To optimize the microwave assisted extraction technology of icariin from Epimedii Folium. METHODS： The microwave assisted extraction technology of icariin from Epimedii Folium was optimized by L9（34）orthogonal design using extraction temperature, extraction time, alcohol concentration,ratio of solid and liquid with the content of icariin as index. RESULTS： The optimal extraction process of icariin was as follows： extraction temperature of 60 ℃,extraction time of 6 min, 30% alcohol and ratio of solid and liquid was 1 ∶ 20. CONCLUSION： The extraction technology is high efficiency and requires short period for extraction of icariin from Epimedii Folium with low cost.
