RESUMO
This paper reports the antimutagenic activity of plumbagin (5-hydroxy-2-methyl-1, 4-naphthoquinone) against certain known chemical mutagens in a standard mutagenicity test system of Ames using S. typhimurium strains. Plumbagin by itself did not show any mutagenic effect, whereas it reduced significantly the mutagenic effect of 4-nitrophenylene diammine, phenyl hydrazine and sodium azide in test strains of S. typhimurium, suggesting that plumbagin possessed antimutagenic activity.
