| Description | 2-(3,4-Dihydroxyphenyl)-3,5,6,7-tetrahydroxy-4H-chromen-4-one, also known as 6-hydroxyquercetin or 3,3',4',5,6,7-hexahydroxyflavone, belongs to the class of organic compounds known as flavonols. Flavonols are compounds that contain a flavone (2-phenyl-1-benzopyran-4-one) backbone carrying a hydroxyl group at the 3-position. Thus, 2-(3,4-dihydroxyphenyl)-3,5,6,7-tetrahydroxy-4H-chromen-4-one is considered to be a flavonoid lipid molecule. A hexahydroxyflavone that is flavone substituted by hydroxy groups at positions 3, 5, 6, 7, 3' and 4' respectively. 2-(3,4-Dihydroxyphenyl)-3,5,6,7-tetrahydroxy-4H-chromen-4-one is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 2-(3,4-Dihydroxyphenyl)-3,5,6,7-tetrahydroxy-4H-chromen-4-one is a bitter tasting compound. Outside of the human body, 2-(3,4-dihydroxyphenyl)-3,5,6,7-tetrahydroxy-4H-chromen-4-one has been detected, but not quantified in, sweet oranges. Quercetagetin is found in Acacia catechu , Achyrocline tomentosa, Actinocephalus polyanthus, Tagetes erecta , Alnus glutinosa, Anthemis cotula, Anthemis spp., Artemisia nova, Artemisia tridentata, Brickellia cylindracea, Brickellia microphylla, Chrysanthemum spp., Citrus aurantium, Citrus reticulata, Citrus sinensis, Cupressus sempervirens, Eriocaulon spp., Eupatorium gracile, Glechoma hederacea, Helichrysum stoechas, Hymenoxys scaposa, Leucaena glauca , Leucanthemum atratum, Neurolaena lobata, Paepalanthus polyanthus, Paepalanthus ramosus, Paepalanthus robustus, Platycodon grandiflorus, Rhaponticum carthamoides , Rudbeckia hirta, Senecio oryzetorum, Tagetes lucida, Tagetes minuta, Tagetes patula , Tagetes subulata, Tagetes tenuifolia and Viguiera dentata. Quercetagetin was first documented in 2010 (PMID: 20685402). This could make 2-(3,4-dihydroxyphenyl)-3,5,6,7-tetrahydroxy-4H-chromen-4-one a potential biomarker for the consumption of these foods (PMID: 22223143) (PMID: 23000494) (PMID: 23142567). |
