摘　　要：响应面法优选新疆红芪多糖提取工艺。以新疆红芪多糖提取率为参考指标,在提取温度、时间、料液比进行单因素实验的基础上,利用响应面法优选提取条件。最佳优化提取工艺为提取温度88.77℃,提取时间2.83 h,料液比1∶30.24(g/mL),在该优化条件下,新疆红芪精制多糖的实际提取率为3.56%。利用响应面法优化新疆红芪多糖提取工艺是合理可行的。The response surface method was optimized for the extraction of polysaccharides from Xinjiang red peony.The extraction rate of polysaccharides from Xinjiang red peony was used as a reference index.Based on the single factor experiment of extraction temperature,time and solid-liquid ratio,the response surface method was used to optimize the extraction conditions.The optimum extraction process was as follows:extraction temperature was 88.77°C,extraction time was 2.83 h,and the ratio of material to liquid was 1∶30.24(g/mL).Under the optimized conditions,the actual extraction rate of Xinjiang red peony polysaccharide was 3.56%.It is reasonable and feasible to optimize the extraction process of Xinjiang red peony polysaccharide by response surface methodology.
