Gambogic acid is a xanthonoid that is derived from the brownish or orange resin from Garcinia hanburyi. Garcinia hanburyi is a small to medium-sized evergreen tree (up to approximately 15 m in height) with smooth grey bark. It is native to Cambodia, southern Vietnam, and Thailand and has been successfully introduced in Singapore.
