摘要：

Three new isoflavanones, named (3 R)-5,7,2',3'-tetrahydroxy-4'-methoxy-5'-prenylisoflavanone, (3R)-7,2',3'-trihydroxy-4'-methoxy-5'-prenylisoflavone and (3S)-3,7,2',3'-tetrahydroxy-4'-methoxyny-5'-prenylisoflavanone were isolated from the stembark of Geoffroea decorticans. The structures were confirmed by means of spectral analysis including 2D-NMR techniques. (C) 1998 Elsevier Science Ltd. All rights reserved.
