To detect naturally occuring antimutagenic substances from wild mushrooms in Korea, the screening for the antimutagenic compounds containing in ethanol and water extracts of 13 wild mushrooms toward benzo(a) pyrene (B(a)P) and $N-methyl-N'-nitro-N-nitrosoguanidine\;(MNNG)$ using the Ames assay system with Salmonella typhimurium TA98 and TA100 were studied. The ethanol extracts of Polyporus dispansus, Cantharellus infundibuliformis, Agaricus subrutilescens, Daedalea dickinsii, Panaeolus papilionaceus and Hydnum repandum showed significantly antimutagenic activity toward B(a)P. The water extracts of Hydnum repandum showed the strong antimutagenic activity toward B(a)P in S. typhimurium TA100, however the water extracts of the mushrooms did not show antimutagenic activity. Whereas 5 out of 13 samples exhibited antimutagenicity toward a direct mutagen of MNNG. The water extracts from mushrooms also not showed antimutagenic activity. The antimutagenic effect increased with increasing concentraion of the ethanol extracts from Polyporus dispansus.
