摘要
在单因素试验基础上,采用响应面法的(Box-Benhnken)组合设计原理,对淫羊藿总黄酮的提取工艺参数进行优化。淫羊藿总黄酮的最佳提取工艺条件为:提取时间1.73 h、水料比31∶1(mL/g),温度67.5℃、乙醇浓度79%,淫藿黄酮类化合物的平均提取率为2.054%,比理论预测值高0.08%。
On the basis of single factor experiment,the conditions for extracting flavonoids from Herba Epimedii were optimized with response surface method （RSM）. The optimal conditions for flavones extraction were obtained as follows： extraction temperature of 67.5℃ ,water/solid ratio of 31, extraction time of 1.73 h,and ethanol concentration of 79%. Under the above conditions,the one-time extraction rate was up to 2.054%,which was 0.08% more than the theoretical value.
