甘草酸单钾盐(KGA)是从豆科植物百草中提取的主要有效成分,有广泛的药理作用。本文采用毛细管法,测定不同浓度的KGA溶液的表面张力σ,求出临界胶团浓度(CMC)。从甘草中提取KGA纯品,再用75%乙醇重结晶2
Monopotassium glycyrrhizinate (KGA) is the main active ingredient extracted from the leguminous herbaceous herbs and has extensive pharmacological effects. In this paper, capillary method was used to determine the surface tension σ of different concentrations of KGA solution and the critical micelle concentration (CMC) was obtained. Extraction of pure KGA from licorice and recrystallization with 75% ethanol 2
