摘　　要： 以石崖茶为原料,采用响应面法优化微波法提取类黄酮的工艺.在单因素实验的基础上,分别选定料液比、乙醇浓度和微波处理时间3个水平进行响应面实验,通过回归分析得到优化组合条件.结果表明,石崖茶类黄酮微波法提取的最佳工艺条件为:料液比1︰30,乙醇浓度60%,微波处理时间3 min,类黄酮提取率的理论预测值为33.6%,验证值为33.7%,两者相差不大,即该优化方法可行. Response surface analysis methodology（RSM） was applied Io optimize Ihe microwave-assisted extraelion eomlitinns of flawmoids from Adinmmdra nil, ida. A~：eording to the singh： factor experiments, three levels of the factors（the ratio of＇ mah：rial to solvent, ethanol concentration and microwave treatment lime） were selected for the factorial design to esLablish a quadric regression equation for describing the yieht of llawmoids. By response surl＇aee analysis, the optimum extraction conditions were ol）tained as follows： I.he ratio of material to solvenl 1：30, ethanol cnneentralion 60%, microwave treatment lime 3min. The average yield of fiavonoids was 33.7% by validation experiments, while Ihe predieted yieht was 33.6%, and the results demonstrated that this method was feasible.
