Metabolite Identification
Common NameO-Demethylforbexanthone
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 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. Based on a literature review very few articles have been published on O-Demethylforbexanthone.
