Effect of test phytochemicals (150 μM) on the modulation of DBP (10 μM)-induced DNA adducts in vitro using salmon testes DNA and β-nathpthaflavone-induced rat liver microsomes by 32P-postlabeling. Total adduct levels in the presence of test agents were compared to vehicle (corn oil + 20% DMSO) control and were significantly different if p < 0.05 (n = 3–8) (**p < 0.001; ***p < 0.0001).
