The title compound, C(29)H(48)O, is a triterpenoid isolated from Adiantum incisum forssk. In the crystal structure, the asymmetric unit contains two independent mol­ecules which are not significantly different. Each mol­ecule contains four six-membered rings, all adopting chair conformations, and a...

description The title compound, C(29)H(48)O, is a triterpenoid isolated from Adiantum incisum forssk. In the crystal structure, the asymmetric unit contains two independent mol­ecules which are not significantly different. Each mol­ecule contains four six-membered rings, all adopting chair conformations, and a five-membered ring in an envelope conformation. In the mol­ecular structure, non-classical intra­molecular C—H⋯O hydrogen bonds are observed.
