The salts of 3-acetyl-18β-glycyrrhetinic acid can be prepared by reaction
between 3-acetyl-18β-glycyrrhetinic acid and an aluminum alcoholate.
Preferably lower alcoholates are used, i.e., alcoholates in which the alkoxy
group or groups have from one to four carbon atoms. The salification reaction
may be carried out at room temperature or at an elevated temperature in
conventional fashion, preferably in the presence of organic solvents. As
organic solvents may be used alcohols, ethers, ketones, chlorinated solvents
(methylene chloride, chloroform) ethyl acetate, etc.
