Figure 3: Rat dermal fibroblast viability was investigated by an 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay. Cells were incubated with various concentrations of H2O2for 24 h following a 2-h pretreatment with (a) crude anthocyanins extract at 10 or 25 μg/mL or (b) purified anthocyanins extract at 10 or 25 μg/mL. The percent increase in cell viability after a 2-h pretreatment with anthocyanins from (c) crude ANT extract or (d) purified ANT extract is shown. Data are expressed as the mean ± standard deviation of three independent experiments. *P < 0.05, **P < 0.01 and ***P < 0.001
