Folk medicine Terminalia catappa and its major tannin component, punicalagin, are effective against bleomycin-induced genotoxicity in Chinese hamster ovary cells.
Terminalia catappa L. is a popular folk medicine for preventing hepatoma and treating hepatitis in Taiwan. In this paper, we examined the protective effects of T. catappa leaf water extract (TCE) and its major tannin component, punicalagin, on bleomycin-induced genotoxicity in cultured Chinese hamster ovary cells. Pre-treatment with TCE or punicalagin prevented bleomycin-induced hgprt gene mutations and DNA strand breaks. TCE and punicalagin suppressed the generation of bleomycin-induced intracellular free radicals, identified as superoxides and hydrogen peroxides. The effectiveness of TCE and punicalagin against bleomycin-induced genotoxicity could be, at least in part, due to their antioxidative potentials.
