12α-Hydroxy-3,27-dioxooleanano-28,13-lactone

There are two independent molecules in the asymmetric unit of the title compound, C30H44O5. They comprise a triterpenoid skeleton of five six-membered rings and a five-membered lactone ring. The five six-membered rings are all trans-fused. In both independent molecules the D rings adopt a slightly d...
