摘要
通过对槐米总黄酮提取,考察体积分数、提取时间、提取温度、料液比四因素对槐米总黄酮提取率的影响。用RAS软件程序对试验数据进行二次响应面分析,对3项工艺参数进行优化,得出槐米总黄酮提取的二次回归方程;通过分析得出槐米总黄酮提取的最佳条件为:60%乙醇(体积分数),提取2.2h,料液比(g:mL)1:17.9,温度80.0℃。在此条件下测得的总黄酮提取率为18.46%。
The effects of volume, time, temperature, the ratio of solid-fluid （g：mL）, on the yield of total flavone were studied and the parameters for optimum yield were obtained by using RAS softwave. The results showed that the optimum parameters was： 60 percent ethanol volume, 2.2 h,1：17.9 （g： mL）,temperature80.0 ℃. In this situation,the extraction yield of total flavone is 18.46 %.
