STPE reverses the UVB-induced decrease in cell viability. The effects of (a) STPE and (b) UVB at different concentrations or dose on L929 cell viability, and (c) the protective effects of STPE on L929 cell damage by UVB (20 mJ/cm2). The error bars refer to the standard deviations obtained from six sample analyses. The data were analyzed by one-way ANOVA followed by LSD post-hoc test. Means with “*” differ significantly (p < 0.05)
