<div><p>Two new xanthones, designated garcimangosxanthone F (<b>1</b>) and garcimangosxanthone G (<b>2</b>), were isolated from the EtOAc-soluble fraction of ethanolic extract from the pericarp of <i>Garcinia mangostana</i>. Their structures were established as 1,6,7-trihydroxy-5-(3-methylbut-2-enyl)-8-(3-hydroxy-3-methylbutyl)-6′,6′-dimethylpyrano[2′,3′:3,2]xanthone and 1,6,7-trihydroxy-5-(3-methylbut-2-enyl)-8-(3-hydroxy-3-methylbutyl)-6′,6′-dimethyl-4′,5′-dihydropyrano[2′,3′:3,2]xanthone, respectively, on the basis of their 1D, 2D NMR and MS data interpretation.</p></div>
