    摘要: In a triterpenic acid having hydroxyl groups, at least one of the hydroxyl groups is phosphorylated to produce a phosphorylated triterpenic acid and/or a salt thereof, thereby improving the solubility of the triterpenic acid in a preparation for external application for the skin and allowing the physiological activity of the triterpenic acid to be exerted satisfactorily. The phosphorylated triterpenic acid is preferably, for example, ursolic acid phosphate and/or a salt thereof. The preparation for external application for the skin is preferably a cosmetic, particularly preferably a quasi-drug.

    摘要: A method of efficiently extracting a high-purity stereoisomer from a mixture comprising the endo isomer and the exo isomer of a dicarboxylic acid having a norbornene or norbornane structure, or a derivative thereof. The present invention relates to a method of separating the endo isomer and the exo isomer of a dicarboxylic acid represented by a general formula (1) or (2) or a derivative thereof, and includes the step of stirring and mixing a mixture comprising mainly the endo isomer of the dicarboxylic acid represented by the general formula (1) or (2) or a derivative thereof, and the exo isomer of the dicarboxylic acid represented by the general formula (1) or (2) or a derivative thereof, with a basic compound and a solvent. (wherein, R1 to R8 represent a hydrogen atom, methyl group, ethyl group, or butyl group), (wherein, R′1 to R′10 represent a hydrogen atom, methyl group, ethyl group, or butyl group).
