DescriptionO-Demethylforbexanthone belongs to the class of organic compounds known as pyranoxanthones. These are organic aromatic compounds containing a pyran or a hydrogenated derivative fused to a xanthone ring system. O-Demethylforbexanthone is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, O-Demethylforbexanthone has been detected, but not quantified in, fruits and herbs and spices. This could make O-demethylforbexanthone a potential biomarker for the consumption of these foods.
