摘要: 在单因素试验的基础上,利用响应曲面法对灰树花多糖提取工艺参数进行优化研究。响应面分析结果表明,提取温度、提取时间以及水料比与响应值灰树花多糖得率存在显著的相关性,通过典型性分析得到优化灰树花多糖提取条件:提取温度为89.7℃;时间2.48h;以及水料比31.1:1,提取两次,在此条件下灰树花多糖提取得理论值达到10.62%,验证试验条件下实际最大多糖得率为(10.13±0.7)%。

Abstract: In this work, based on the results of one–factor-at-a-time-technique method, a three-level Box-Behnken factorial design was employed combining with response surface methodology (RSM) to optimize the extraction conditions for the yield of Grifola frondosa polysaccharides (GFPS). A mathematical model was then developed to show the significant effect of each factor and their interactions on the yield of GFPS. Canonical analysis was used to estimated that a maximal yield of polysaccha- rides (10.62%) could be obtained when the extraction conditions of temperature, time and ratio of water to material were set at 89.7℃, 2.48h and 31.1:1, respectively with two-time extraction. These predicted values were also verified by validation experiments.

Key words: Grifola frondosa polysaccharides (GFPS), response surface methodology, Box-Behnken design, optimization
