Abstract:
In the title compound, C(46)H(80)O(3), 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, mol-ecules are linked by O-H⋯O hydrogen bonds, forming chains along [010].
