Natural Product Identification

Common Name

2-(3,4-Dihydroxyphenyl)-3,7,8-trihydroxy-4H-1-benzopyran-4-one

Description

Melanoxetin 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, melanoxetin is considered to be a flavonoid lipid molecule. 2-(3,4-Dihydroxyphenyl)-3,7,8-trihydroxy-4H-1-benzopyran-4-one is found in Acacia confusa, Vachellia karroo, Acacia karroo , Acacia melanoxylon , Acacia montana, Acacia salicina, Albizia adianthifolia , Albizia lebbek, Pterocarpus santalinus and Acacia nigrescens. Melanoxetin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
