摘　　要：采用响应面分析法对水飞蓟多糖的提取工艺进行优化。在单因素试验的基础上,根据Box-Benhnken中心组合试验设计原理,以水料比、提取温度、提取时间为自变量,多糖提取率为响应值,采用3因素3水平响应面分析法进行分析。试验结果表明,水飞蓟多糖的最佳提取工艺为:水料比35∶1(m L/g)、提取温度73℃、提取时间3.75h。在此条件下,多糖提取率可达到6.58%。The extracting process of Silybum marianum polysaccharides was optimized by using response surface analysis.Based on single factor test,the ratio of water to material,extraction temperature and extraction time were selected as independent variables with the response of polysaccharide extraction yield,three-level three-factor Box-Benhnken design was applied to determine the effect of central composite experimental design.The test results showed that the optimal extraction conditions were as follows：the ratio of water to material 35：1（mL/g）,extraction temperature 73 ℃,extraction time 3.75 h.The extraction rate of polysaccharides was 6.58%under these conditions.
