8-Demethylthymonin
5,6,8-trihydroxy-2-(4-hydroxy-3-methoxyphenyl)-7-methoxy-3,4-dihydro-2H-1-benzopyran-4-one
8-demethylthymonin is a member of the class of compounds known as 7-o-methylated flavonoids. 7-o-methylated flavonoids are flavonoids with methoxy groups attached to the C7 atom of the flavonoid backbone. 8-demethylthymonin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 8-demethylthymonin can be found in common thyme, which makes 8-demethylthymonin a potential biomarker for the consumption of this food product.
