摘　　要：通过正交方法分析回流次数、乙醇浓度、回流时间、料液比对连翘叶总黄酮得率的影响。结果表明:连翘叶中总黄酮的最佳提取方案是:回流3次,料液比1:6,乙醇浓度55%,每次回流时间60min。总黄酮的得率为10.79%,回收率为104%,RSD=0.75(n=3)。Through orthogonal test, the influences of factors like circumfluence times, ethanol concentration, circumfluence time and ratio of solid to liquid in extraction on total flavones were analyzed. Result showed that the optimum extracting approach was to use 3 times of circumfluence, ratio of solid to liquid to be 1 to 6. 55% of ethanol concentration and 60mins per circumfluence. The total flavones by extraction eventually reached 10.79% and recovery rate at 104% plus RSD at 0.75（n=3）.
