Figure 1: Cytotoxicity of purple corn silk extract on HaCaT cells (a) at various concentrations of purple corn silk extract. (b) At various ultraviolet-B -energy levels. (c) Images of HaCaT cells treated with purple corn silk and ultraviolet-B at ×20. (d) Histogram show percentage of cell viability treated with purple corn silk and ultraviolet-B. Results are the mean values ± standard deviation of three independent experiments. *P < 0.05 versus non- ultraviolet-B group and #P < 0.05 versus the ultraviolet-B-control group
