A new polyoxygenated dimer-type xanthone, namely 5,5′-oxybis(1,3,7-trihydroxy-9H-xanthen-9-one (1), has been isolated from the stem bark of Garcinia porrecta. The structure of 1 was determined based on spectroscopic data, including 1D and 2D-NMR as well as high resolution mass spectroscopy analysis.
