摘　　要：据有关研究表明中药杜仲中含有一定量的多糖,并且多糖类物质具有许多重要的生理功能。通过在3组单因素试验的基础上,将料液比、提取时间、乙醇浓度结合响应面,进一步优化提取条件,通过结果分析得出最佳的提取工艺,即在料液比为1∶60(g/mL)、提取时间为40 min、乙醇浓度为60%时,杜仲多糖的提取率为44.53%,为最高提取率。为杜仲多糖的提取及后续研究提供依据。According to relevant studies,Eucommia ulmoides contains a certain amount of polysaccharides,and polysaccharides have many important physiological functions.On the basis of three groups of single factors,the extraction conditions are further opti‐mized by combining the material liquid ratio,extraction time and ethanol concentration with the response surface.The best extrac‐tion process is material liquid ratio 1:60(g/mL),the extraction time 40 min and the ethanol concentration is 60%,the extraction rate of Eucommia ulmoides polysaccharide is 44.53%,which is the highest extraction rate.
