摘 要：
采用回流、超声波、微波等提取方法以及单因素试验,研究白补药总黄酮适宜提取方法及其因素水平。在这基础上,设计正交试验以优化白补药总黄酮的提取工艺,试验结果表明微波提取白补药总黄酮最佳提取条件为:功率400 W,料液比1∶40,乙醇质量分数50%,提取时间2min,提取次数为2次,在此工艺条件下,白补药中总黄酮提取率为9.28%。

摘 要：
To select and optimize the flavonoid extraction technology on Salvia scapiformis Hance harvested from Mt.Leigong in Guizhou,various factor levels on an orthogonal experimentwere tested using reflux,ultrasound,and microwave in the process.The results showed that the microwave extraction method was the best among all,with a9.28% yield on total flavonoids.The optimal conditions for the processincluded a 2-minute application of microwave power at 400 W with asolid:liquid ratio of 1∶40and the use of 50%ethanol.And,the extraction procedureswere repeated to maximize the substance recovery.
