Figure 1. Protective effect of the ethyl acetate fraction obtained from Zanthoxylum bungeanum leaves on H2O2-induced cytotoxicity in PC12 cells. Pretreated with different concentration of the ethyl acetate fraction (ZLE) for 3 h before exposure to 1.0 mM H2O2 for 1 h, the viability of PC12 cells were determined by MTT reduction assay. Data are presented as the mean ± SD (n = 3). * P < 0.05 vs. H2O2 only, **P < 0.01 vs. H2O2 only
