QKL activated AMPK and decreased oxidative stress levels. a Western blot analysis of p-AMPK, AMPK and GAPDH. b Quantitative analysis of the p-AMPK: AMPK expression ratio. c Effect of QKL on the SOD level. d Effect of QKL on the MDA level. Data points indicate means ± SEM. Vs Sham group, # < 0.05, ### < 0.001, Vs MCAO group, * p < 0.05, ** p < 0.01. At least three independent experiments were performed for each group
