The TQSS and EPSI drugs inhibited the viability of PC12 cells. a The cell viability of PC12 cells incubated for 48 h with TQSS derived from Shenghui soup at different concentrations (10, 20, 50, 100, 200, 500 and 2000 mg/L). b PC12 cells were treated with different concentrations (5, 10, 20, 50, 100, 200 and 500 mg/L) of EPSI derived from Shenghui soup for 48 h. Data are expressed as mean ± SD, n = 3, *p < 0.05, **p < 0.01, ***p < 0.001 versus control without drugs
