This study was conducted to investigate the antimutagenic effects of methyl alcohol extracts from Auricularia auricula and Gyrophora esculenta on the SOS response induced by 4-nitroquinoline-1-oxide (4NQO), N-methyl-N'-nitro-N-nitrosoguanidine (MNNG), mitomycin C (MMC) and 3-amino-1,4- dimethyl-5H-pyrido-[4,3-b]indol (Trp-P-1) in E. coli PQ37/plasmid pKM101. In the mutagenic test on test strain, both methyl alcohol extracts did not show mutagenic activity. In the antimutagenic test, each sample strongly inhibited the mutagenecity induced by 4NQO, MNNG, MMC and Trp-P-1. Methyl alcohol extracts from Auricularia auricula and Gyrophora esculenta showed inhibitory effects of 52% and 59% against 4NQO, 49% and 58% against MNNG, 53% and 64% against MMC, and 61% and 64% against Trp-P-1, respectively. Gyrophora esculenta extracts on the antimutagenicity showed relatively higher inhibitory effects than that of Auricularia auricula.
