目的 研究甘草及其活性成分的表面活性，為更合理地研究甘草中成分的增溶能力提供參考。方法 在不同溫度下，采用Wilhelmy吊片法測定溶液的表面張力和溶液的臨界膠束濃度（CMC）。結(jié)果 分析了溶液的表面活性效能、效率和表面過剩濃度，甘草水煎液表面活性較好。結(jié)論 甘草中除皂苷組分具有表面活性外，其他組分對表面活性有貢獻(xiàn)。

Objective To study the surface activity of Glycyrrhiza Radix and its active ingredients, and provide the reference for solubilizing capabilities of Glycyrrhiza Radix and its active ingredients. Methods The Wilhelmy plate method was used to determine the surface tension of the aqueous solutions of monoammonium glycyrrhizinate, glycyrrhizinate; saponins in Glycyrrhiza Radix, and Glycyrrhiza Radix, and the critical micelle concentration (CMC) at different temperatures. Results The efficiency, efficacy and surface concentration were analyzed, and the surface activity of the solution of Glycyrrhiza Radix was better. Conclusion There are other components to contribute to the surface activity of Glycyrrhiza Radix solutions except saponins in Glycyrrhiza Radix.
