Chemical Information
FooDB NameLiquiritigenin
DescriptionLiquiritigenin, also known as 5-deoxyflavanone or DFV, belongs to the class of organic compounds known as flavanones. Flavanones are compounds containing a flavan-3-one moiety, with a structure characterized by a 2-phenyl-3,4-dihydro-2H-1-benzopyran bearing a ketone at the carbon C3. Thus, liquiritigenin is considered to be a flavonoid lipid molecule. Liquiritigenin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Liquiritigenin is a bitter tasting compound. Liquiritigenin has been detected, but not quantified in, several different foods, such as peach (var.), rowanberries, common cabbages, common hazelnuts, and oyster mushrooms. This could make liquiritigenin a potential biomarker for the consumption of these foods.
