摘要：

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