在单因素试验的基础上,采用正交L_9(3~4)试验法,以红腺忍冬花为原料,优化其绿原酸的微波提取工艺.考察微波功率、料液比、提取次数、提取时间和溶剂pH值对提取效果的影响,实验结果表明:红腺忍冬绿原酸的最佳微波提取工艺条件为按1:12(g:mL)的料液比加入pH 3的水溶液进行微波辅助提取2次,每次5 min,红腺忍冬山银花中绿原酸提取率可达到4.54%,与传统提取方法相比,该工艺具有提取时间极短、耗能少和提取较高等优点。

The extracting process of chlorogenic acid from Lonicera hypoglauca Miq. with microwave-assisted method was optimized. Oahogonal design L9 （34） method was applied to study the effect of five factors such as microwave power, ratio of material/solvent, extraction duration, time of extraction and solvent pH on the extraction efficiency based on the experimental result of single factor method. The results have shown that optimum conditions of mi- crowave power, solvent pH, ratio of material/solvent, extraction duration and time of extraction were...
