However, the genotoxicity data on crocin are not sufficient for safety evaluation. The purpose of this study was the examination of the genotoxicity on crocin from gardenia yellow in bacterial and mammalian cells, using various genotoxic battery testing assays and the influence of crocin on methyl methanesulfonate (MMS) and H2O2-induced DNA damage in vitro, using single cell gel electrophoresis (comet) assay. From results, no considerable mutagenicity and clastogenicity were seen in bacteria and mammalian cells treated with crocin, by Ames test, chromosomal aberration assay, tk(+/-) gene forward mutation assay and comet assay. And, post-treatment with crocin significantly suppressed H2O2-induced DNA damage in a dose-dependent manner. In conclusion, the findings,of the present study and other previous observations indicate that crocin has no genotoxic potential. And it showed that crocin clearly repressed the genotoxic potency of H2O2. These results suggest that anti-oxidative effects of crocin may be involved in the protective effects of DNA damage.
