Protective effects of Sal-B, Pue and Sal-B + Pue in CoCl2 injured PC12 cells. (a) The viability of PC12 cells induced with different concentration (0.1, 0.2, 0.4, 0.6, 0.8, 1, 1.2, 1.5, 2, 3 mmol·L−1) of CoCl2 for 24 h (** p < 0.01 vs. control group); (b) The viability of PC12 cells pretreated with various concentrations of Sal-B (1, 50, 60, 70, 80, 90, 100 μg·mL−1) and (c) Pue (0.1, 1, 10, 50, 100, 200, 400 μg·mL−1) for 1 h before induced by CoCl2 (* p < 0.05; ** p < 0.01 vs. control); (d) The viability of PC12 cells pretreated with Sal-B (70 μg·mL−1) and Pue (100 μg·mL−1) simultaneously for 1 h before induced by CoCl2. Data were expressed as mean ± SD (n = 6), * p < 0.05 vs. Sal-B or Pue; ** p < 0.01 Sal-B + Pue vs. blank control.
