PROBLEM TO BE SOLVED: To provide a method of producing sphingo base in which sugar-ceramide is used as a row material, a method by which sugar-sphingosine can be selectively produced with high yield by hydrolyzing sugar-ceramide, and a method by which sphingo base can be selectively produced with high yield by hydrolyzing sugar-sphingosine.SOLUTION: The method of producing sugar-sphingosine is provided which includes obtaining sugar-sphingosine by hydrolyzing sugar-ceramide. The hydrolysis includes heating sugar-ceramide at a temperature of 100°C or higher under the presence of aqueous solution of alcoholic organic compound and alkali metal hydroxide, having a boiling point of 100°C or higher to obtain sugar-sphingosine. The method of producing sphingo base is also provided which includes obtaining sphingo base by hydrolyzing sugar-sphingosine. The hydrolysis includes causing sugar hydrolase to act on sugar-sphingosine to obtain sphingo base, and sugar-sphingosine may be produced by the method.SELECTED DRAWING: None |
