• The properties of the third hyhroxyl group in metagenin (I) and epimetagenin (IIIa) were examined. From the results of acylation reaction and acid treatment, it was confirmed that the third hydroxyl group in metagenin had an equatorial and the epimeric one in epimetagenin had an axial conformation. Metagenin formed a δ-lactone ring by the opening of A-ring and was approximately confirmed as 5β, 25D-spirostane-2β, 3β, 11α-triol.
