The modifying effects of the aqueous extract of saffron (dried stigmas of Crocus sativus Linn.) on cisplatin (CIS), cyclophosphamide (CPH), mitomycin-C (MMC) and urethane (URE) induced alterations in lipid peroxidation and antioxidant status were investigated in Swiss albino mice. Three doses of saffron (20, 40 and 80 mg/kg body weight) were orally administered to mice for 5 consecutive days prior to administration of genotoxins. A significant reduction in the extent of lipid peroxidation with a concomitant increase in the liver enzymatic (SOD, CAT, GST, GPx) and non-enzymatic antioxidants (reduced glutathione) were observed in saffron pretreated animals compared with the genotoxins alone treated animals. However, the modulatory effects were not always dose dependent. Our data suggest that saffron may exert its chemopreventive effects by modulation of lipid peroxidation, antioxidants and detoxification systems.Copyright 2003 John Wiley & Sons, Ltd.
