Chemical Information
FooDB NameIsorhamnetin
DescriptionIsorhamnetin, also known as 3-methylquercetin, 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, isorhamnetin is considered to be a flavonoid lipid molecule. Isorhamnetin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Isorhamnetin is a bitter tasting compound. Isorhamnetin is found, on average, in the highest concentration within a few different foods, such as parsley, green bell peppers, and dills and in a lower concentration in garden cress, black chokeberries, and honey. Isorhamnetin has also been detected, but not quantified in, several different foods, such as dandelions, gingers, strawberries, fenugreeks, and guava. This could make isorhamnetin a potential biomarker for the consumption of these foods.
