Metabolite Identification
Common 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. Prunetin is a bitter tasting compound. Prunetin has been detected, but not quantified in, several different foods, such as green tea, prunus (cherry, plum), red tea, black tea, and herbs and spices. This could make prunetin a potential biomarker for the consumption of these foods. Prunetin is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on Prunetin.
