按改进文献方法提取甘草酸,用甘草酸和氨基酸在70%乙醇水溶液中,pH≈5和60 ℃的水浴上反应制备复盐.通过元素分析、热重、红外、紫外光谱分析对复盐进行表征,确定复盐的组成,分别为:C6H15N2O2)2·HG、(C6H10N3O2)2·HG、(C6H15N4O2)2·HG,为进一步研究甘草在中药复方中的功效提供参考.

The liquorice acid was extracted by an improved method. The complex salt of liquorice acid with amino acid was synthesized in 70 % ethanol solution at pH ≈ 5 and 60 ℃. The salts were analyzed by elementaly analysis, IR, UV-Vis and thermogravimetric methods.Their formula are （C6H15N2O2）2·HG, （C6H10N3O2）2·HG and （C6H15N4O2）2·HG respkectively. The property of the complex salt was tested. The work is useful for further study on the e...
