TL;DR
Three new isoflavanones, isolated from the stembark of Geoffroea decorticans, were confirmed by means of spectral analysis including 2D-NMR techniques.
Abstract
Three new isoflavanones, named (3R)-5,7,2′,3′-tetrahydroxy-4′-methoxy-5′-prenylisoflavanone, (3R)-7,2′,3′-trihydroxy-4′-methoxy-5′-prenylisoflavanone and (3S)-3,7,2′,3′-tetrahydroxy-4′-methoxy-5′-prenylisoflavanone were isolated from the stembark of Geoffroea decorticans. The structures were confirmed by means of spectral analysis including 2D-NMR techniques.
