MTT assay of neuronal PC12 cell viability in response to 24 h incubation with H2O2 (400 µM), alone or in the presence of (A) GT, (B) OT, (C) BT and (D) WT extracts (50, 100 or 150 μg/mL). * p < 0.05, ** p < 0.01, *** p < 0.01, **** p < 0.0001 vs. vehicle. # p < 0.05, ## p < 0.01, ### p < 0.001 vs. H2O2 alone. & p < 0.05 vs. H2O2 + 50 μg/mL tea extracts. Results were expressed as mean ± standard deviation (n = 4).
