Effect of AE on attenuating β-secretase. SK-N-MC cells were incubated for 24 h with or without palmitate, and with different concentrations of F1 and F2, thereby analyzed with β-secretase activity. Data were presented as means ± SD (n = 3), and analysed with ANOVA. *p < 0.05, **p < 0.01, ***p < 0.001, compared with the control. #p < 0.05, #p < 0.01, #p < 0.001 compared with the palmitate-treated only
