Antimutagenic activity of ganebu-K (line) and yamabudo (dotted line) towards MeIQx (a), IQ (b), Trp-P-2(NHOH) (c), DMBA (d), and MNNG (e-f) mutagenicity. MeIQx and IQ were assayed with S. typhimurium TA98 with +S9 (a-b), Trp-P-2(NHOH) was assayed with S. typhimurium TA98 with -S9 (c), DMBA was assayed with S. typhimurium TA100 with +S9 (d), and MNNG was assayed with S. typhimurium TA1535 with -S9 (e) and YG7108 with -S9 (f). SD is indicated by bars (n = 3)
