Corniculatusin

Description

3,3',4',5,7-Pentahydroxy-8-methoxyflavone, also known as 8-methoxyquercetin or corniculatusin, 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, 3,3',4',5,7-pentahydroxy-8-methoxyflavone is considered to be a flavonoid lipid molecule. Corniculatusin is found in Centaurea africana, Citrus reticulata, Dryas octopetala , Humata pectinata, Lotus corniculatus , Prosopidastrum globosum and Sedum fusiforme. 3,3',4',5,7-Pentahydroxy-8-methoxyflavone is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
