Chemical Information

FooDB Name

Prunetin

Description

Prunetin, 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 herbal tea, red clovers (Trifolium pratense), black tea, herbs and spices, and teas (Camellia sinensis). This could make prunetin a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Prunetin.
