Natural Product Identification
Common Name5-Hydroxy-7-methoxy-2-(4-methoxyphenyl)-6-methyl-4H-1-benzopyran-4-one
Description5-Hydroxy-4',7-dimethoxy-6-methylflavone, also known as 2-hydroxybenzoic acid or 8-demethyleucalyptin, 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, 5-hydroxy-4',7-dimethoxy-6-methylflavone is considered to be a flavonoid lipid molecule. 5-Hydroxy-4',7-dimethoxy-6-methylflavone is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, 5-Hydroxy-4',7-dimethoxy-6-methylflavone has been detected, but not quantified in, a few different foods, such as beverages, herbs and spices, and tea. 5-Hydroxy-7-methoxy-2-(4-methoxyphenyl)-6-methyl-4H-1-benzopyran-4-one is found in Abies spectabilis, Artemisia austriaca, Callistemon citrinus, Callistemon juniperinus, Callistemon lanceolatus, Callistemon rigidus, Callistemon salignus, Callistemon salignus var.viridiflorus, Callistemon speciosus, Callistemon spp. , Callistemon teretifolius, Corymbia torelliana, Eucalyptus torelliana, Gaultheria procumbens , Kalmia spp. and Lophostemon palustre. This could make 5-hydroxy-4',7-dimethoxy-6-methylflavone a potential biomarker for the consumption of these foods.
