Metabolite Identification
Common Name5-Demethoxynobiletin
Description5-demethoxynobiletin, also known as 3'4'678-pentamethoxyflavone, is a member of the class of compounds known as 8-o-methylated flavonoids. 8-o-methylated flavonoids are flavonoids with methoxy groups attached to the C8 atom of the flavonoid backbone. 5-demethoxynobiletin is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). 5-demethoxynobiletin can be found in winter savory, which makes 5-demethoxynobiletin a potential biomarker for the consumption of this food product.
