The method of response surface analysis was adopted to optimize the extraction conditions of total flavonoids form Lilium pumilum bulb on the basis of single-factor experiment. The results showed that the optimum technological conditions were ethanol concentration of 73%, material-liquid ratio of 32∶1 , reflux temperature of 69 ℃ and reflux time of 120 min. Under such conditions,the actual value of total flavonoids extracted was 4. 685 mg/g,which was basically coincident with the predicted value 4. 729 mg/g. RSD was 0. 661%,indicating that the optimum process conditions were reliable.%在单因素试验的基础上，采用响应面法优化山丹鳞茎总黄酮提取工艺条件。结果表明，山丹鳞茎总黄酮提取最佳工艺为乙醇体积分数73%、料液比32∶1(mL/g)、回流温度69℃、回流时间120 min。经证明，总黄酮含量试验值(4.685 mg/g )与预测值(4.729 mg/g )基本一致， RSD 为0.661%，表明所得工艺参数可靠。
