摘要
以淡肤根石耳为原料,对多糖类成分提取工艺进行了研究,采用单因素实验法对影响多糖提取率的主要因素进行了分析,利用正交实验优化了提取多糖的最佳工艺条件。研究表明,淡肤根石耳中提取多糖类成分的最佳条件为:乙醇浓度95%,提取温度80℃,料液比1:20,提取时间3.0h,在最佳条件下多糖的提取率为15.07%。
The extraction technology of polysaccharides from Umbilicaria virginis Schaer.was studied.Main factors influencing the extraction of polysaccharides from the Umbilicaria virginis Schaer.were studied by single factor experiments,and the optimum technology extracting polysaccharides from Umbilicaria virginis Schaer.was studied by orthogonal test.Optimized conditions for the extraction of polysaccharides was obtained as：ethanol concentration 95%;extraction temperature 80 ℃;material-water ratio 1：20;extraction time 3.0 h;and extract yield is 14.57%.
