Effect of quercetin on HepG2 cells viability. Cells were treated with Quercetin at concentrations of 82.5, 165, 330, and 660 μM for 24 and 48 h. Data are expressed as a percentage of the control group ± the standard error of the mean of three replicates from three independent experiments. Statistical significance was assessed by multiple t test followed by Holm–Sidak correction for multiple comparisons; * p < 0.05, ** p < 0.01, *** p < 0.001.
