Description | 3,5-Dihydroxy-2-(4-hydroxy-3-methoxyphenyl)-7-methoxy-4H-chromen-4-one, also known as 3',7-dimethylquercetin or 3,5,4'-trihydroxy-7,3'-dimethoxyflavone, 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, 3,5-dihydroxy-2-(4-hydroxy-3-methoxyphenyl)-7-methoxy-4H-chromen-4-one is considered to be a flavonoid lipid molecule. A dimethoxyflavone that is quercetin in which the hydroxy groups at the 3' and 7 positions have been replaced by methoxy groups. 3,5-Dihydroxy-2-(4-hydroxy-3-methoxyphenyl)-7-methoxy-4H-chromen-4-one is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, 3,5-dihydroxy-2-(4-hydroxy-3-methoxyphenyl)-7-methoxy-4H-chromen-4-one has been detected, but not quantified in, lemon balms. Rhamnazin is found in Achyrocline alata, Achyrocline tomentosa, Aeonium spp., Aesculus hippocastanum , Alnus japonica, Ambrosia trifida, Ammi visnaga, Argyrochosma nivea, Artemisia campestris , Artemisia gmelinii, Artemisia monosperma, Blumea balsamifera, Callicarpa kwangtungensis, Capparicordis tweediana, Capparis tweediana , Cistus incanus, Cistus laurifolius, Cistus spp., Escallonia pulverulenta, Eucalyptus globulus, Eucryphia jinksii, Garcinia bracteata, Garcinia dulcis , Geranium macrorrhizum , Grindelia nana, Halocnemum strobilaceum, Hazardia squarrosa, Heliotropium stenophyllum, Heterotheca villosa, Kitaibela vitifolia, Laggera alata, Larrea cuneifolia , Madia elegans, Wedelia biflora , Miliusa horsfieldii, Mirabilis viscosa, Mutisia orbignyana, Myricaria alopecuroides, Nasturtium officinale, Nervilia fordii, Nothofagus cunninghamii, Notholaena neglecta, Notholaena nivea, Nymphoides geminata, Orthosiphon spicatus, Oxytropis sylvatica, Palhinhaea cernua, Passiflora palmeri, Pericome caudata, Persicaria hydropiper, Polanisia dodecandra, Polygonum polystachyum, Polygonum punctatum , Retama sphaerocarpa, Rhamnus alaternus , Rhamnus cathartica , Rhamnus disperma, Rhamnus lycioides, Rhamnus prinoides , Rhamnus saxatilis, Salpiglossis sinuata, Siegesbeckia jorullensis, Stevia subpubescens, Traversia baccharoides and Viscum cruciatum . Rhamnazin was first documented in 2001 (PMID: 11594002). This could make 3,5-dihydroxy-2-(4-hydroxy-3-methoxyphenyl)-7-methoxy-4H-chromen-4-one a potential biomarker for the consumption of these foods (PMID: 25704088) (PMID: 27025066). | Read more...
