描述
5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4h-chromen-4-one, also known as 3',5'-O-dimethyltricetin or 5,7,4'-trihydroxy-3',5'-dimethoxy-flavone, is a member of the class of compounds known as 3'-o-methylated flavonoids. 3'-o-methylated flavonoids are flavonoids with methoxy groups attached to the C3' atom of the flavonoid backbone. Thus, 5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4h-chromen-4-one is considered to be a flavonoid lipid molecule. 5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4h-chromen-4-one is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4h-chromen-4-one can be synthesized from tricetin. 5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4h-chromen-4-one is also a parent compound for other transformation products, including but not limited to, tricin 7-O-glucoside, 4'-O-beta-glucosyl-7-O-(6-O-sinapoylglucosyl)tricin, and tricin 7-O-(6''-O-malonyl)-beta-D-glucopyranoside. 5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4h-chromen-4-one can be found in barley, common wheat, oat, and rice, which makes 5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4h-chromen-4-one a potential biomarker for the consumption of these food products.
