Figure 2. Cytotoxicity of pinosylvin in ARPE-19 cell line. ARPE-19 cells were exposed to pinosylvin (0.1–200 µM) for 24 h before cytotoxicity was determined in the cell viability test. Data as mean value±standard deviation (SD), n = 6. *p<0.05, significantly different from untreated cells (0 µM), ANOVA, and the t test.
