Abstract
In the title compound, C46H80O3, a natural ursane-type triperpenoid, four of the five six-membered rings adopt chair conformations; the fifth, which has a C=C double bond, adopts an approximate half-boat conformation. In the crystal, molecules are linked by O—H...O hydrogen bonds, forming chains along [010].
