Chemical Information
FooDB NameAcacetin
Description5,7-dihydroxy-2-(4-methoxyphenyl)-4h-chromen-4-one, also known as 4'-methoxy-5,7-dihydroxyflavone or acacetin, is a member of the class of compounds known as 4'-o-methylated flavonoids. 4'-o-methylated flavonoids are flavonoids with methoxy groups attached to the C4' atom of the flavonoid backbone. Thus, 5,7-dihydroxy-2-(4-methoxyphenyl)-4h-chromen-4-one is considered to be a flavonoid lipid molecule. 5,7-dihydroxy-2-(4-methoxyphenyl)-4h-chromen-4-one is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 5,7-dihydroxy-2-(4-methoxyphenyl)-4h-chromen-4-one can be synthesized from apigenin. 5,7-dihydroxy-2-(4-methoxyphenyl)-4h-chromen-4-one is also a parent compound for other transformation products, including but not limited to, acacetin-7-O-beta-D-galactopyranoside, acacetin-8-C-neohesperidoside, and isoginkgetin. 5,7-dihydroxy-2-(4-methoxyphenyl)-4h-chromen-4-one can be found in ginkgo nuts, orange mint, and winter savory, which makes 5,7-dihydroxy-2-(4-methoxyphenyl)-4h-chromen-4-one a potential biomarker for the consumption of these food products.
