Metabolite Identification
Common NameCoixinden B
DescriptionCoixinden B 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 B has been detected, but not quantified in, several different foods, such as black tea, green tea, arabica coffees (Coffea arabica), herbal tea, and teas (Camellia sinensis). This could make coixinden b a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Coixinden B.
