Vol. 1, p.552 (1941) - preparation of xanthone〕 In 1939, xanthone was introduced as an insecticide and it currently finds uses as ovicide for codling moth eggs and as a larvicide.〔Steiner, L. F. and S. A. Summerland. 1943. Xanthone as an ovicide and larvicide for the codling moth. ''Journal of economic entomology'' 36, 435-439.〕 Xanthone is also used in the preparation of xanthydrol, which is used in the determination of urea levels in the blood. ==Xanthone derivatives== The chemical structure of xanthone forms the central core of a variety of naturally occurring organic compounds, such as 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. They are also found in some species of the genus ''Iris''. 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''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Xanthone」の詳細全文を読む スポンサード リンク
