Abstract
Two new xanthones, designated garcimangosxanthone F (1) and garcimangosxanthone G (2), were isolated from the EtOAc-soluble fraction of ethanolic extract from the pericarp of Garcinia mangostana. 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.
Keywords: Garcinia mangostana; xanthone; garcimangosxanthone F; garcimangosxanthone G
