甘草是我国民间常用的补益中药,成分较复杂,除含甘草酸(甘草甜素)外,尚有许多其它成分,各种成分功能不一。本实验仅采用了其中成分之一——L_x。从本实验的化学组成分析结果来看,L_x亦为一复合体,含有蛋白质、核酸、多糖,尚含有少量鞣酸及甘草酸。文献报告L_x有抑制IgG产生 Licorice is a commonly used tonic medicine in China, and its components are more complex. In addition to glycyrrhizic acid (glycyrrhizin), there are many other ingredients that have different functions. Only one of the components, L_x, was used in this experiment. From the chemical composition analysis results of this experiment, L_x is also a complex containing protein, nucleic acid, and polysaccharide, and still contains a small amount of tannic acid and glycyrrhizic acid. Literature reports that L_x inhibits IgG production
