Summary
Eight xanthones and a biphenyl have been isolated from the dichloromethane extract ofKielmeyera coriacea (Guttiferae) stem bark by a combination of centrifugal partition chromatography and gel filtration on Sephadex LH-20, with HPLC-UV monitoring of fractions. The structures of the isolated compounds (Figure 1) were established by spectroscopic methods (UV, EI-MS, D/CI-MS,1H NMR,13C NMR).
