Description	In this work antimutgenic effects of some of plant extracts with high content of flavonoids and carotenoids and their active components were analyzed using Saccharomyces cerevisiae D7 strain. This test is commonly used to evaluate genotoxicity of various substances. Most of plant foods exhibited positive (20 - 40% of inhibition) or high positive (more than 40%) antimutagenic activity. High positive antimutagenicity exhibited extracts of spinach (65%), broccoli (58%) and Chlorella (54%).
