dc.description.abstractMutagenicity and antimutagenicity potentials were tested using Ames' test in crude distilled water and absolute ethanol extracts from the stems and leaves of Peperomia pellucida (Linn.) Kunth, Eichhornia crassipes Solms, Colocasia esculenta Schott and Brachiaria mutica (Forssk.) Stapf, and the stems of Musa sapientum Linn. No mutagenic effect was found in any of the 10 mg/plate crude extracts of these plants for either TA98 or TA100 of Salmonella typhimurium, in a direct test and a mutagenic induced test by S-9 mix. Both distilled water and absolute ethanol extract of 0.5-10 mg/plate B. mutica showed strong antimutagenicity to AFB1, B(a)P and 4NQO in two tester strains. Ethanol extract of 0.1-0.5 mg/plate C. esculenta also showed antimutagenicity to AFB1, B(a)P and 4NQO in two tester strains, but the 0.5-10 mg/plate water extract had an antimutagenic effect only for B(a)P in TA98. The ethanol extracts of 5 mg/plate B. mutica and 0.5 mg/plate C. esculenta are cytotoxic, as indicated by their partial killing effect.en_US
