Natural Product Identification
Common Name5,6,7,8-Tetramethoxy-2-phenyl-4H-1-benzopyran-4-one
Description5,6,7,8-Tetramethoxyflavone belongs to the class of organic compounds known as 8-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C8 atom of the flavonoid backbone. Thus, 5,6,7,8-tetramethoxyflavone is considered to be a flavonoid lipid molecule. 5,6,7,8-Tetramethoxy-2-phenyl-4H-1-benzopyran-4-one is found in Godmania aesculifolia, Helichrysum herbaceum, Helichrysum nitens, Lindera lucida, Nothofagus cunninghamii and Zeyhera tuberculosa. 5,6,7,8-Tetramethoxyflavone is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
