Luteolin, also known as 3',4',5,7-tetrahydroxyflavone or digitoflavone, is a member of the class of compounds known as flavones. Flavones are flavonoids with a structure based on the backbone of 2-phenylchromen-4-one (2-phenyl-1-benzopyran-4-one). Thus, luteolin is considered to be a flavonoid lipid molecule. Luteolin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Luteolin is a bitter tasting compound and can be found in a number of food items such as squashberry, chinese cabbage, spearmint, and red huckleberry, which makes luteolin a potential biomarker for the consumption of these food products. Luteolin can be found primarily in blood. Luteolin is a flavone, a type of flavonoid, with a yellow crystalline appearance .
Belongs to the class of organic compounds known as flavones. These are flavonoids with a structure based on the backbone of 2-phenylchromen-4-one (2-phenyl-1-benzopyran-4-one).
