Chemical Information
FooDB NameGalangin
DescriptionNorizalpinin, also known as teptochrysin or galangin, 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, norizalpinin is considered to be a flavonoid lipid molecule. Norizalpinin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, Norizalpinin is found, on average, in the highest concentration within mexican oregano. Norizalpinin has also been detected, but not quantified in, several different foods, such as lingonberries, garden onion (var.), herbs and spices, parsley, and apples. This could make norizalpinin a potential biomarker for the consumption of these foods. A 7-hydroxyflavonol with additional hydroxy groups at positions 3 and 5 respectively; a growth inhibitor of breast tumor cells.
