1-(5a,5b,8,8,11a,13b-Hexamethyleicosahydro-1H-cyclopenta[a]chrysen-3-yl)-1-ethanone

The title compound, C29H48O, 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-m...
