Metabolite Identification
Common Name7-Hydroxy-3,3',4',5,6-pentamethoxyflavone
Description7-hydroxy-3,3',4',5,6-pentamethoxyflavone is a member of the class of compounds known as 6-o-methylated flavonoids. 6-o-methylated flavonoids are flavonoids with methoxy groups attached to the C6 atom of the flavonoid backbone. Thus, 7-hydroxy-3,3',4',5,6-pentamethoxyflavone is considered to be a flavonoid lipid molecule. 7-hydroxy-3,3',4',5,6-pentamethoxyflavone is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 7-hydroxy-3,3',4',5,6-pentamethoxyflavone can be found in common bean, green bean, sweet orange, and yellow wax bean, which makes 7-hydroxy-3,3',4',5,6-pentamethoxyflavone a potential biomarker for the consumption of these food products.
