Chemical Information
FooDB NamePrunetin
DescriptionPrunetin, also known as padmakastein, belongs to the class of organic compounds known as 7-o-methylisoflavones. These are isoflavones with methoxy groups attached to the C7 atom of the isoflavone backbone. Thus, prunetin is considered to be a flavonoid lipid molecule. Prunetin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Prunetin is a bitter tasting compound. Prunetin has been detected, but not quantified in, several different foods, such as herbs and spices, prunus (cherry, plum), sour cherries, and tea. This could make prunetin a potential biomarker for the consumption of these foods.
