| 摘 要： | 在百部多糖提取体系中，利用响应面分析法(response surface methodology)对在单因素试验基础上选取的提取温度、液料比、提取时间三个主要因素，以百部多糖得率为响应值，对其工艺进行了优化。得出百部多糖水提取的最佳工艺条件为：提取温度83℃，液料比33:1(V/m)，提取时间200min，百部多糖的实际提取率为3.74％，比单因素试验最高提取率高出11.31％。

| Abstract: | On the basis of single-factor tests, extraction temperature, ratio of hot water to crushed raw material, extraction time affecting extraction rate of Radix stemonae polysaccharides (RSP) were optimized using response surface methodology (RSM). The results showed that the optimum temperature, ratio of liquid to solid, time of RSP extraction are 83 ℃, 33:1 and 200 min, respectively. Under these conditions, the extraction rate of RSP is up to 3.74%, which is higher 11.31% than the highest one in single-factor tests. |
