Abstract
Ginseng saponin metabolites produced by human intestinal bacteria were evaluated for antigenotoxic properties by testing their effects on benzo[a]pyrene (B[a]P)-induced mutagenicity and clastogenicity. They include 20-O-(β-D-glucopyranosyl)-20(S)-protopanaxadiol (IH-901), 20-O-[α-D-arabinopyranosyl(1→6)-β-D-glucopyranosyl]-20(S)-protopanaxadiol (IH-902) and 20-O-[α-D-arabinofuranosyl(1→6)-β-D-glucopyranosyl]-20(S)-protopanaxadiol (IH-903). IH-901, IH-902 and IH-903 inhibited the mutagenicity of B[a]P in a dose-dependent manner. In the chromosome aberration assay, IH-901 and IH-903 reduced the frequency of chromosome aberration induced by B[a]P. These results suggest that the ginseng saponin metabolites tested in the present study have potential as chemopreventive agents.
