Metabolite Identification
Common Name8-Methoxycoumarin
Description8-methoxycoumarin, also known as 8-methoxy chromen-2-one, belongs to coumarins and derivatives class of compounds. Those are polycyclic aromatic compounds containing a 1-benzopyran moiety with a ketone group at the C2 carbon atom (1-benzopyran-2-one). 8-methoxycoumarin is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 8-methoxycoumarin can be found in common wheat, which makes 8-methoxycoumarin a potential biomarker for the consumption of this food product. 8-methoxycoumarin is found in Herniaria glabra, Ayapana triplinervis and in species of the genus Prunus (P. mahaleb, P. pensylvanica, and P. maximowiczii) .
