title: Isolation of a p-hydroxyphenyl anhydride from the leaves of Diphysa carthagenensisw.
abstract: Diphysidione (1), a new p-hydroxyphenyl anhydride, and vitexin (2) were isolated from the leaves of Diphysa carthagenensis. The structure of the new metabolite was characterised as 4-(4-hydroxy-phenyl)-3H-pyran-2,6-dione using 1D and 2D NMR spectroscopy.
