Oligomeric and polymeric procyanidins were isolated from grape seeds, and their antimutagenic potential against food carcinogens was evaluated in the Ames test. Both procyanidins suppressed the mutagenicity of IQ and benzo[a]pyrene but did not modulate the mutagenic activity of MNNG. At the concentr
