Effects of EEF and BuF on the activity of SOD (a), CAT (b), GSH-Px (c) and T-AOC (d) in PC12 cells under hypoxia condition. PC12 cells are pre-incubated with 500 μg/L EEF or BuF for 1 h prior to hypoxia for 24 h. ^##p < 0.01 vs. control. ^**p < 0.01 vs. hypoxia. Data are shown as mean ± SD (n = 6). Rutin is used as positive control
