Effects of various concentrations of SAHE (a), SADE (b), and linariin (c) on cell viability of PC12 cells after 24 h in comparison to the control group. Effects of pretreatment with various concentrations of SAHE (a’), SADE (b’), and linariin (c’ )on H2O2-induced cytotoxicity in PC12 cells. All experiments were done in triplicate. The data is presented as the mean ± SEM. The significance of the difference is presented as * p < 0.05, ** p < 0.01, *** p < 0.001
