| 摘 要： | 目的]优化微波辅助提取山茱萸（FRUCTUS CORNI）多糖的提取工艺。方法]在全面单因素试验的基础上,先采用Plackett-Burman设计对7个因素进行试验,筛选出影响最大的3个因子,并确定其余因素的最优水平,再利用响应面法设计对3个主要因子进行试验和优化,建立了二次多项式数学模型。结果]微波功率、液料比和乙醇体积分数是主要因子,最佳工艺条件是：山茱萸粉末直径在300~450μm之间,料液比1∶19.7（g∶m l）,微波功率624 W,辐照时间55 s,水浴温度90℃,浸提时间2 h,乙醇体积分数为68.4%,在此条件下,多糖得率达20.94%。结论]该方法误差小、数据可靠,可用于山茱萸多糖的提取。

| Abstract: | Objective] To optimize the microwave-assisted extraction technology of polysaccharides from FRUCTUS CORNI.Method] Firstly,the most 3 influential factors were selected by Plackett-Burman design test with 7 factors on the basis of single-factor test,and the optimum levels of other factors were determined.Secondly,a quadratic polynomial model was established from experimental data that was obtained from the optimization of three main factors by response surface design.Result] The microwave power,solid-liqui... |
