Xanthone is an molecular formula C13H8O2. It can be prepared by the heating of phenyl salicylate.[2] In 1939, xanthone was introduced as an insecticide and it currently finds uses as ovicide for codling moth eggs and as a larvicide.[3] Xanthone is also used in the preparation of xanthydrol, which is used in the determination of urea levels in the blood.

Xanthone derivatives

The mangostin, which are sometimes collectively referred to as xanthones or xanthonoids. Over 200 xanthones have been identified. Many xanthones are phytochemicals found in plants in the families Bonnetiaceae, Clusiaceae, Podostemaceae, and others.[4] They are also found in some species of the genus Iris.[5] Some xanthones are found in the pericarp of the mangosteen fruit (Garcinia mangostana) as well as in the and bark and timber of Mesua thwaitesii.[6]
