Ten previously undescribed compounds, including five prenylated xanthones (1-5), two caged xanthones (16-17) and three rearranged benzophenones (27-29), together with nineteen known compounds were isolated from the fruits of Garcinia bracteata. Their structures were established on the basis of spectroscopic analysis, electronic circular dichroism calculations, and X-ray crystallographic data. Compound 17 was a caged xanthone bearing a rare 8, 8a-epoxy moiety. Compound 28 belonged to the rearranged benzophenones with rare 2, 7-dioxab
