本研究采用响应曲面法对影响GLP提取率的三个主要影响因素即提取温度、提取时间和液固比进行了优化.利用Design Expert软件对GLP提取率的二次多项数学模型分析表明:在提取温度为89.35℃,提取时间1.47h,液固比29.19:l时,GLP提取率较高,最佳提取率预测值为0.776%,与实测值基本相符.利用优化工艺参数提取GLP时,可获得最大的提取率.
Optimization of Extraction Process of Ganoderma lucidum Fruitbody Polysaccharides by Response Surface Methodology
The effects of different temperature,time and the ratio of solid to solution on the extraction yield of Ganoderma lucidum polysaccharides(GLP)were optimized with response surface methodology.Experimental data were analyzed by the regression equation with Design Expert(Version 6.0.2) software.It indicated that the optimum extraction parameters are temperature89.35℃,time 1.47 hand the ratio of solid to solution 1:29.19. Under these conditions,the predicted value of GLP extraction yield is 7.76mg/g, in consistent with the measured value.It is the maximal extraction yield of GLP with optimized process parameters.
