| description | 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-membered ring in an envelope conformation. In the molecular structure, non-classical intramolecular C—H...O hydrogen bonds are observed. |
