以甘草多糖为研究对象,利用苯酚-硫酸法测定其多糖含量,溶剂的种类、浸提温度、浸提时间、液固比和提取次数为实验因素,最后以粗甘草多糖产率为指标进行实验研究.最终确定提取甘草多糖的最佳工艺条件为：最佳溶剂为水,浸提温度为80℃,液固比（ml/g）为30：1,提取时间4小时,提取次数2次.实验还采用sevag法除蛋白,活性炭脱色对甘草粗多糖进行分离纯化,并用紫外分光光度法检测蛋白质是否除尽.大侠们帮帮忙

人工,放心使用吧.
Polysaccharide in glycyrrhiza was the object of research ,using Phenol-Sulfuric Acid method to determine its content of polysaccharide.The experiment factors were the varieties of the solvent ,the extraction temperature ,the extraction time ,liquid-solid ratio and extraction times ,and the target of test was the yields of coarse polysaccharide in glycyrrhiza .Finally ,the the optimum technological conditions of extraction for polysaccharide in glycyrrhiza show that the optimum solvent was water ,extraction temperature 80℃ ,solid to liquid ratio 30:1,extraction time 4 h and 2 times .Sevag in experiment removed albumen,Polysaccharide were decontaminated by active carbon ,and Ultraviolet Spectrophotometry examined the remaind of proteid .
