Natural Product Identification
Common Name4',7-Dimethoxy-6,8-dimethyl-5-hydroxyflavone
DescriptionEucalyptin 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, eucalyptin is considered to be a flavonoid lipid molecule. 4',7-Dimethoxy-6,8-dimethyl-5-hydroxyflavone is found in Angophora lanceolata, Angophora subvelutina, Callistemon lanceolatus, Eucalyptus cinerea, Eucalyptus cladocalyx, Eucalyptus robusta, Eucalyptus saligna, Eucalyptus torelliana, Eugenia biflora, Kalmia latifolia , Myrcia citrifolia and Syncarpia glomulifera. Eucalyptin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
