摘要
采用响应曲面法对超声波辅助提取库拉索芦荟凝胶中的多糖提取工艺参数进行优化研究。考察超声时间、提取液pH值、液料比对芦荟多糖提取率的影响,并建立数学模型。利用Design-Expert软件对数据进行回归分析,得到芦荟多糖提取率的二次多项式回归方程的预测模型。结果表明,库拉索芦荟多糖超声辅助提取的优化工艺条件为:超声时间为45.85min、提取液pH值为8.74、液料比为29.84mL/g,在此条件下的库拉索芦荟多糖提取率为11.453mg/g。
Response surface methodology （RSM）was applied to optimize the ultrasonic-assisted extraction conditions of polysaccharides from Aloe barbadensis （ABPS）gel.Experimental design was used to investigate the effect of three parameters （extraction time,pH value,ratio of water to raw material）on polysaccharides yields.The regression equation of the relationship between the three factors were also established.The predictive model of polynomial quadratic equation was analyzed by Design-Expert software.The results indicated that the optimum extraction conditions of the Aloe barbadensis polysaccharides were as follows： ultrasonic extraction time 45.85 min,pH value 8.74,ratio of water to material 29.84 mL/g.Under the optimized condition,the predicted yield of polysaccharides extracted was 11.453 mg/g.
