**5. Conclusion**

Our results indicate that, PCA was more efficient that GA to reduce DNA damage induced by food mutagens tested. PCA at the concentrations tested protect human hepatoma derived cells against DNA strand breaks induced by NDMA, NPYR, BaP and PhIP, oxidized pyrimidines induced by NDMA NPYR, NPIP, BaP, PhIP and oxidized purines induced by NDBA, NDMA, NPYR, NPIP, MeIQx and diMeIQx.. However, GA at the concentrations tested only protects human hepatoma cells against DNA strand breaks induced by BaP, oxidized pyrimidines induced by NDMA and BaP and oxidized purines induced by NDMA, NPYR, NPIP, PhIP, MeIQx and diMeIQx.
