| Description | 3,7-Dimethylquercetin, also known as DTHF, belongs to the class of organic compounds known as 7-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C7 atom of the flavonoid backbone. Thus, 3,7-dimethylquercetin is considered to be a flavonoid lipid molecule. 3,7-Dimethylquercetin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 3,7-Dimethylquercetin exists in all living organisms, ranging from bacteria to humans. Outside of the human body, 3,7-Dimethylquercetin is found, on average, in the highest concentration within grape wines and beers. This could make 3,7-dimethylquercetin a potential biomarker for the consumption of these foods. 2-(3,4-Dihydroxyphenyl)-5-hydroxy-3,7-dimethoxy-4H-1-benzopyran-4-one is found in Aeonium manriquiorum, Ageratina havanensis, Artemisia monosperma, Artemisia spp. , Baccharis pilularis, Blumea balsamifera, Calceolaria spp., Chrysothamnus viscidiflorus, Croton schiedeanus, Cyperus spp., Dioscorea bulbifera, Eirmocephala megaphylla, Eriodictyon trichocalyx, Eucryphia milliganii, Eucryphia moorei, Flourensia cernua, Grindelia tarapacana, Haplopappus taeda, Heliotropium pycnophyllum, Heliotropium stenophyllum, Holocarpha spp., Lantana camara , Larrea cuneifolia , Larrea divaricata , Larrea tridentata , Macaranga triloba, Wollastonia biflora, Mimulus cardinalis, Mirabilis viscosa, Nolana rostrata, Ozothamnus lycopodioides, Ozothamnus scutellifolius, Palafoxia sphacelata, Pelargonium fulgidum , Pelargonium quercifolium , Petunia surfinia, Rubus phoenicolasius , Salpiglossis sinuata, Siegesbeckia jorullensis, Siegesbeckia orientalis , Solanum pennellii, Taxus chinensis, Viscum album , Viscum cruciatum , Vitex agnus-castus, Vitis vinifera, Wallastonia bifora and Xanthocephalum gymnospermoides. 2-(3,4-Dihydroxyphenyl)-5-hydroxy-3,7-dimethoxy-4H-1-benzopyran-4-one was first documented in 1989 (PMID: 2632060). A dimethoxyflavone that the 3,7-di-O-methyl derivative of quercetin (PMID: 19031255). |
