In the present study, the putative potential of pericarp of dried fruit of Zanthoxylum (Rutaceae Family), a common spice additive in India's west coast cuisines, in protecting against carcinogenesis has been reported. Extract from dried fruit of Zanthoxylum was orally administered to mice at two dose levels: 100 and 200 mg/kg body wt. for 14 days. Results reveal bifunctional nature of Zanthoxylum species as deduced from its potential to induce phase-I and phase-II enzyme activities associated with carcinogen activation and detoxification in the liver of mice. Hepatic glutathione S-transferase and DT-diaphorase were found significantly elevated by the treatment. Zanthoxylum was also effective in augmenting the antioxidant enzyme activities of glutathione peroxidase, superoxide dismutase and catalase albeit significantly by high dose of the extract (P < 0.05; P < 0.01). Reduced glutathione was also significantly elevated in the liver of treated animals (P < 0.05). The present study also investigated peri-initiation application of acetone extract of Zanthoxylum on initiated mouse skin. Results showed a significant reduction in tumor incidence from 68% to 36% (P < 0.05); as well as, a reduction in tumor burden per effective mouse from 3.87 to 0.72 (P < 0.01). Cumulatively, the findings strongly suggest cancer chemopreventive potential of Zanthoxylum sps. 相似文献
