ellagic acid

A potent antagonist of the mutagenicity induced by bay region diol oxides or aromatic hydrocarbons (e.g., the ultimate carcinogenic metabolite of benzo[a]pyrene). Ellagic acid is present in cherries, strawberries and grapes, and may explain in part the anticarcinogenic effects of a fruit-rich diet.
