Water bath extraction method was used to optimize the extraction conditions of quercetin from the citrus peel. Combining single factor test and Orthogonal experiment , the optimum extraction conditions were chosen as follows:solid (g):liquid (mL)=1:50, ethanol=80%, extracting temperature 80℃, extracting time 3.5 h. Under the optimize conditions, the extraction efficiency of quercetin was 9.685%.%采用水浴提取法优化柑橘皮中槲皮素提取的最佳条件,在单因素试验的基础上,采用正交试验优化提取工艺,确定了提取槲皮素的最佳条件:料液比1:50(g/mL),乙醇浓度80%,水浴温度80℃,水浴时间3.5 h.在此条件下,柑橘皮中槲皮素的提取率为9.685%.
