Rabdoternins D-G, ent-7β,20-epoxykaurenes from Rabdosia ternifolia

Abstract Examination of the diterpenoid constituents of the dried leaves of Rabdosia ternifolia led to the isolation of four new diterpenoids, named rabdoternins D-G. The structures were elucidated on the basis of spectroscopic and chemical evidence.
