MTT assay results of six ginsenosides on the proliferation of RAW264.7 cells induced by LPS (a) and HUVEC cells induced by TNF-α (b) as a function of concentrations for 24 h. DMSO and MTX was served as a negative group and a non-ginsenoside positive control group, respectively. Data are presented as the mean ± SD (n = 6). *p < 0.05, vs DMSO group; ^ap < 0.05, vs CK group
