Effect of α-cyperone on H₂O₂-induced cell apoptosis. After being pretreated with α-cyperone (15 or 30 μM) for 2 h, SH-SY5Y cells were stimulated with H₂O₂ (200 μM) for 24 h. (A–F) The apoptosis were assessed by an Annexin V-FITC/PI Apoptosis Detection Kit. All experiments were repeated at least three times and similar results were obtained. Data are presented as the mean ± SE, (n= 5 samples per group). ^##p < 0.01 vs. the control group, ^*p < 0.05 vs. the H₂O₂-treated group.
