Xanthone is an organic compound with the molecular formula C13H8O2. It can be prepared by the heating of phenyl salicylate. In 1939, xanthone was introduced as an insecticide and it currently finds uses as ovicide for codling moth eggs and as a larvicide. Xanthone is also used in the preparation of xanthydrol, which is used in the determination of urea levels in the blood.
The chemical structure of xanthone forms the central core of a variety of naturally occurring organic compounds, such as mangosteen, which are sometimes collectively referred to as xanthones or xanthonoids. Over 200 xanthones have been identified. Xanthones are natural constituents of plants in the families Bonnetiaceae and Clusiaceae and are found in some species in the family Podostemaceae. Many of these xanthones are found in the pericarp of the mangosteen fruit (Garcinia mangostana), and bark, timber of Mesua thwaitesii, which can be found in the region of Southeast Asia.
