Abstract
Three new isoflavanones, named (3 R)-5,7,2',3'-tetrahydroxy-4'-methoxy-5'-p renylisoflavanone, (3R)-7,2',3'-trihydroxy-4'-methoxy-5'-prenylisoflavone a nd (3S)-3,7,2',3'-tetrahydroxy-4'-methoxyny-5'-prenylisoflavanone were isol ated from the stembark of Geoffroea decorticans. The structures were confir med by means of spectral analysis including 2D-NMR techniques. (C) 1998 Els evier Science Ltd. All rights reserved.
