Effect of lycopene obtained of tomato paste (A), tomato extract (B), tomato sauce (C), and ketchup (D) on DU-145 cell viability after 24, 48, 72, and 96 h of exposure, respectively. The results are expressed as mean ± error standard and significant differences between untreated cells (Control) and those treated with lycopene (500, 1000, 2500, and 5000 µg/mL) were compared by one-way ANOVA followed by Tukey’s multiple comparison post-hoc test. * p < 0.05; ** p < 0.01; *** p < 0.001.
