1-(5a,5b,8,8,11a,13b-Hexamethyl-eicosa-hydro-1H-cyclo-penta-[a]chrysen-3-yl)-1-ethanone.

ABSTRACT: 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 mol-ecules which are not significantly different. Each mol-ecule contains four six-membered rings, all adopting chair conformations, and a five-membered ring in an envelope conformation. In the mol-ecular structure, non-classical intra-molecular C-H⋯O hydrogen bonds are observed.
