Summary, etc. Ecdysantherin, 3/3-hydroxy-20-methylpregn-5,14-dien- 16-one-(18-20)-lactone, C21H2604, a new pentacyclic sap©nine, was isolated from the powder of Ecdysanthera rosea Hook. et Am. (Apocynaceae)of Vietnam, and its structure was elucidated. It was found that ecdysantherin is a pentacyclic sap©nine molecule with three sixmembered and two five-membered rings. An intermolecular OH.-.O hydrogen bond generates infinite chains of molecules in the z direction.
