摘　　要：目的:探寻高纯度香蕉多糖的分离纯化方法。方法:取成熟香蕉,加热提取,乙醇醇沉,真空干燥得香蕉粗多糖,再将香蕉粗多糖溶解,CTAB溶液沉淀,真空干燥得香蕉精多糖。结果:提取溶剂为水;提取次数为2次;加水量为第一次加12倍,第二次加8倍;提取时间为第一次3h,第二次2h;减压浓缩至原有滤液量50%;乙醇醇沉浓度为70%;CTAB溶液终浓度为1.5%;干燥方法为减压干燥。结论:试验结果表明,高纯度的香蕉多糖的分离提取提工艺是可行的。Purpose search for high-purity banana polysaccharide purification method.Methods：From mature bananas,heat extraction,ethanol alcohol,and then vacuum drying,to obtain banana polysaccharide,these banana polysaccharide were dissolved,CTAB precipitation solution,and finally obtained by vacuum drying of banana essence polysaccharide.Results：Extraction solvent was water,extracted twice number,water for the first was 12-fold,and the second was 8-fold,extraction time for the first was three hours,and the second was two hours,decompression filtrate concentrated to the original 50%,the concentration of ethanol precipitation was 70%,final concentration CTAB solution was 1.5%,decompression drying method for drying.Conclusion：Test results show that the high purity of the polysaccharides extracted from the banana to technology is feasible
