DITERPENOIDS FROM RABDOSIA SCULPONEATA

摘要

Five ent-6,7-seco-karuene diterpenoids-enmein,epinodosin,sculponeatin A,C,D,were isolated from thedried leaves of Rabdosia sculponeata One of the compounds,named sculponeatin D,was previously unreported.Itsstructre was elucidated by the spectral data including 2D COSY,1H-13C correlation,2D NOESY spectroscopy.
