Chemical Information
FooDB NameEupatilin
DescriptionEupatilin belongs to the class of organic compounds known as 6-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C6 atom of the flavonoid backbone. Thus, eupatilin is considered to be a flavonoid lipid molecule. Eupatilin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Eupatilin has been detected, but not quantified in, herbs and spices and mandarin orange (clementine, tangerine). This could make eupatilin a potential biomarker for the consumption of these foods.
