title: Caged polyprenylated xanthones from the resin of Garcinia hanburyi.
abstract: Five new caged polyprenylated xanthones (1a, 2a, 3, 10a and 10b), and 12 known related compounds were isolated from the resin of Garcinia hanburyi. Their structures were elucidated by detailed spectroscopic analyses and their α-glucosidase inhibitory activities were investigated in vitro. Most of xanthones showed modest inhibitory activity against α-glucosidase.
