Ethyl acetate, n-butanol and water extracts of C. morifolium were examined for mutagenicity towards strains of Salmonella typhimurium (TA98 and TA100) with or without S9 mix. The ethyl acetate extract showed mutagenicity without S9 mix in TA98, but the mutagenicity was lost with S9 mix. The n-butanol and water extracts showed no mutagenicity in TA98 or TA100 with or without S9 mix.Antibacterial activities of the ethyl acetate extract were examined by using B. cereus, B. subtilis, M. luteus, St. aureus, E. coli, S. enteritidis, TA98 and TA100. This extract showed antibacterial activities towards gram-positive bacterial strains and TA98.
