Metabolite Identification
Common NameCoixinden A
DescriptionCoixinden A belongs to the class of organic compounds known as indenes and isoindenes. Indenes and isoindenes are compounds containing an indene moiety(which consists of a cyclopentadiene fused to a benzene ring), or a isoindene moiety (which consists of a cyclopentadiene fused to cyclohexadiene ring). Coixinden A has been detected, but not quantified in, several different foods, such as red tea, green tea, arabica coffees (Coffea arabica), herbal tea, and alcoholic beverages. This could make coixinden a a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Coixinden A.
