| 摘 要： | 在黄精多糖提取体系中,利用响应面分析法(response surface methodology)对在单因素试验基础上选取的料液比、提取温度和提取时间三个主要因素,以黄精多糖提取率为响应值,对其提取工艺参数进行优化,得出黄精多糖水提取的最佳工艺条件为:料液比是21.5:1,提取温度:73.5℃,提取时间:2.5h,黄精多糖的实际提取率可达12.25%,比单因素试验最高提取率高出10.6%。

| Abstract: | In this paper, aiming at optimization of the extraction of Polyonatic Sibiricum polysaccharides (PSP), test factors and levels were firstly selected by one-factor tests. On the basis of previous results and according to the central composite test design principles, the method of response surface method (RSM) with 3 factors and 3 levels was adopted. Response surface and contour are finally graphed with the extraction rate of PSP as the response value. The results showed that the optimum conditions of PSP extraction are: ratio of water to water 21.5:1, the extraction temperature 73.5 ℃, extraction time 2.5 h. The extraction rate of PSP is up to 12.25%, and it is higher 10.6% than one-factor tests. |
