Metabolite Identification
Common NameDemethylcalabaxanthone
DescriptionDemethylcalabaxanthone belongs to the class of organic compounds known as 8-prenylated xanthones. These are organic compounds containing a C5-isoprenoid group linked to a xanthone moiety at the 8-position. Xanthone is a tricyclic compound made up of two benzene rings linearly fused to each other through a pyran ring that carries a ketone group. Demethylcalabaxanthone has been detected, but not quantified in, fruits and purple mangosteens (Garcinia mangostana). This could make demethylcalabaxanthone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Demethylcalabaxanthone.
