Effects of hyperoside on the proliferation of melanocytes. (A) Following exposure of melanocytes to various concentrations of hyperoside (0, 0.5, 1, 2, 5, 10, 50, 100 and 200 µg/ml) for 12, 24 and 48 h, cell viability was determined using a tetrazolium bromide assay. Data are expressed as the mean ± standard deviation (n=6), #, ▲P<0.05 and **, ##, ▲▲P<0.01, vs. control.
