摘要
利用双水相分配技术从甘草中提取甘草酸盐,测定了不同分子质量PEG (NH4)2SO4双水相体系的分配系数,并利用改进Diamond Hsu模型对此双水相体系的分配系数进行了数学关联。得到比较好的结果。
Glycyrrhizic salt was extracted from glycyrrhiza by using technique of aqueous twophase. Coefficients of glycyrrhizic monoanmmonium salt in aqueous two\|phase PEG/(NH4)2SO4 systems with different molecular weight of PEG were measured. Based on the modified Diamond\|Hsu model coefficients of glycyrrhizic monoanmmonium salt in aqueous two\|phase PEG/(NH\-4)\-2SO\-4 systems were correlated. It was found that the correlation of the experimental data was very satisfactory.
