摘　　要：分别采用超声波提取法、水提取法、碱提取法提取板栗壳中多糖.在单因素实验的基础上进行正交试验,分别研究了3种方法对板栗壳多糖的提取率.结果表明,3种方法中超声波提取法的提取率较高,为9.15%;其次是水提取法,为5.99%;碱提取法最低,为4.72%.通过SPSS软件分析发现3种方法提取率之间存在显著差异(p<0.01).This study investigated the optimal extraction conditions of chestnut shells polysaccharides by utilizing three different methods, ultrasonic extraction, water extraction, and alkali extraction. The single factor test and orthogonal experiment were adopted to optimize the extraction conditions. The results indicated that the best extracting method was ultrasonic extraction and the polysaccharides is 9. 15%. The yields of polysaccharides from water extraction and alkali extraction were 5.99% and 4.72%. The yields of three methods were significantly different by analyzing with SPSS.
