【 摘 要 】

The title compound, C30H48O2, contains a fused four-ring triterpenoid system. In the mol­ecule, the two cyclo­hexane rings adopt a chair conformation and a twist boat conformation, respectively, the central cyclo­hexene ring adopts a half-chair conformation whereas the five membered ring adopts an envelope conformation. In the crystal, O—H⋯O hydrogen bonds between the hy­droxy and carbonyl groups of adjacent mol­ecules link the mol­ecules into supra­molecular chains propagating along the b-axis direction.
