S-METHYL METHANE THIOSULFONATE, A NEW ANTIMUTAGENIC COMPOUND ISOLATED FROM (BRASSICA OLERACEA)___- L VAR. (BOTRYTIS)___-

抄録

Though various antimutagens with desmutagenic activities have been found in our daily foods of plant origin, the numbers of antimutagens with bio-antimutagenic activities found so far are limited.In the present study, a compound with potential bio-antimutagenic activity to Escherichia coli B/r WP2 was newly isolated from cauliflower, Brassica oleracea L. var. botrytis, and its chemical structure was identified to be S-methyl methane thiosulfonate by NMR and MS analysis.
