摘　　要：为优化瓦尼木层孔菌菌丝体多糖提取工艺,在单因素试验的基础上,以提取温度、提取时间、水料比3个因素为自变量,以瓦尼木层孔菌菌丝体多糖提取率为响应值,使用BOX-Benhnken中心组合试验和响应面分析法,优化瓦尼木层孔菌菌丝体多糖提取工艺,并确定瓦尼木层孔菌菌丝体多糖的最佳工艺条件为:提取温度80.99℃、提取时间2.13 h、水料比32.06∶1(mL/g)。在此条件下,实际提取率为10.49%,与预测值基本吻合。In this study, optimum condition of extraction of polysaccharides from Phellinus vaninii Ljub was optimized by response surface test. On the basis of single-factor test, the mathematical regression model was established on the dependent variable （extraction yield of polysaccharides from Phellinus vaninii Ljub） and independent variables （extract temperature, extract time, water/material ratio） by Box-Benhnken center composite design and response surface methodology. The optimum extraction conditions were as follows： extract temperature 80.99 ℃, extract time 2.13 h, water/material ratio 32.06：1 （mL/g）. Under these conditions, the yield of polysaccharides from Phellinus vaninii Ljub was 10.49 %, consistent with the prediction value.
