Mangiferin, 1,3,6,7-tetrahydroxyxanthone-C2-beta-D-glucoside, is one of xanthone derivatives and C-glucosylxanthones, is widely distributed in higher plants and is one of constituents of folk medicines. Recent studies showed that mangiferin has a potential as an anti-oxidant and an anti-viral agent. In this study, we examined the effects of mangiferin in rat colon carcinogenesis induced by chemical carcinogen, azoxymethane (AOM). We performed two experiments: a short-term assay to investigate the effects of mangiferin on the development of preneoplastic lesions by AOM, aberrant crypt foci (ACF), and the following long-term assay for the influence of mangiferin on tumorigenesis induced by AOM. In the short-term assay, 0.1% mangiferin in a diet significantly inhibited the ACF development in rats treated with AOM compared to rats treated with AOM alone (64.6+/-22.0 vs. 108.3+/-43.0). In the long-term assay, the group treated with 0.1% mangiferin in initiation phase of the experimental protocol had significantly lower incidence and multiplicity of intestinal neoplasms induced by AOM (47.3 and 41.8% reductions of the group treated with AOM alone for incidence and multiplicity, respectively). In addition, the cell proliferation in colonic mucosa was reduced in rats treated with mangiferin (65-85% reductions of the group treated with AOM alone). These results suggest that mangiferin has potential as a naturally-occurring chemopreventive agent.
