Abstract

A dichloromethane extract of the aerial parts of Combretum albopunctatum Suessengafforded five phenolic compounds - three known flavonoids and two novel cyclobutane chalcone dimers. The chemical structures were determined by standard spectroscopic techniques and the structure and relative stereochemistry of one chalcone dimer, rel-(1a,2b)-di-(2,6-dimethoxy-4-hydroxy)-benzoylrel-(3a,4b)-diphenylcyclobutane, were confirmed by single crystal X-ray diffraction.
