Flavone and triterpenoid constituents of Elaegia utilis
Abstract
By neutral solvent extraction of Elaegia utilis resin, there have been isolated the flavone apigenin (12) and the tetracyclic triterpenoid isofouquierol (10), whose structure has been confirmed. Dammarenediol-II (1)(in dimorphic form) and a new triterpenoid, (20S)-dammar-24-ene-3β,20,26-triol (6), were obtained from the neutral nonsaponifiable fraction.
