Chemical Information
FooDB NamePinocembrin
Description(s)-pinocembrin, also known as 5,7-dihydroxyflavanone or dihydrochrysin, is a member of the class of 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 (s)-pinocembrin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). (s)-pinocembrin is a bitter tasting compound found in mexican oregano and tarragon, which makes (s)-pinocembrin a potential biomarker for the consumption of these food products.
