摘要: 为优化水溶性黄连木多糖的提取工艺,在单因素试验的基础上,选取提取温度、提取时间以及水料比为自变量,多糖提取率为响应值,采用中心组合设计的方法,研究各自变量及其交互作用对多糖提取率的影响。利用响应面分析方法,模拟得到二次多项式回归方程的预测模型,并确定水溶性黄连木多糖提取工艺的最佳条件为:温度90℃、时间3h、水料比34:1。在此条件下,多糖提取率达到4.27%。

Abstract: To optimize extraction process of water-soluble polysaccharides from seeds of Pistacia chinensis Bung on the base of single factor investigation,effects of extraction temperature,extraction time and ratio of water to material as well as their interactions on yield of the polysaccharides were studied by central composite design. The predictive polynomial quadratic equations model was developed by response surface analysis. The optimal extraction conditions of the polysaccharides from seeds of Pistacia chinensis Bung are concluded as follows:extraction time 3 hours,temperature 90 ℃ and ratio of water to material 34:1. Under these conditions,the yield of the polysaccharides is up to 4.27%.
