Genotoxicity of tested flavonoids (1–100 μM) and their mixtures containing equal concentrations of each compound (1–100 μM) in HT29 cells evaluated with the aid of comet assay and expressed as %DNA in the comet tail. Results represent means ± SD of three independent experiments. Negative control (C-) refers to cells treated with solvent only. Significantly different values determined by one-way ANOVA with Dunnett's test are marked as: **p ≤ 0.01.
