Description | 5,6-Dihydroxy-7-methoxy-2-phenyl-4H-chromen-4-one 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, 5,6-dihydroxy-7-methoxy-2-phenyl-4H-chromen-4-one is considered to be a flavonoid lipid molecule. Negletein is found in Centaurea clementei, Colebrookea oppositifolia, Desmos chinensis , Desmos cochinchinensis, Desmos dumosus, Elsholtzia ciliata, Mosla chinensis, Ononis angustissima, Origanum dictamnus , Origanum majoricum, Stachys neglecta and Stachys palustris. 5,6-Dihydroxy-7-methoxy-2-phenyl-4H-chromen-4-one is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. |
