Abstract

Extraction of the branches of Garcinia dulcis afforded a xanthone with a novel oxygenation pattern [1,4,6-trihydroxy-5-methoxy-7-(3-methylbut-2-enyl)xanthone] in addition to the triterpenoid friedelin and the known flavonoids 3′-(3-methylbut-2-enyl)naringenin, I3,II8-biapigenin and podocarpusflavoneA. The structures were determined by a combination of 2D homo- and heteronuclear NMR correlation spectroscopy and NOE difference spectroscopy.
