Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a new method for producing a triterpene derivative expressed by formula (II) and usable as a synthetic intermediate for medicines by a biological conversion method. SOLUTION: A triterpene derivative used as a starting material is incubated in the presence of a cultured cell or processed cultured cell of a microorganism capable of converting the starting material to the objective triterpene derivative of formula (II) and the objective compound is separated from the treated liquid. The microorganism is e.g. those belonging to the genus Streptomyces. In the formula, either one of R1and R2is hydrogen atom and the other is hydroxyl group or both groups together form an oxo group.
