The chemical structures of six ginsenoside monomers (a). The MTT assay results of six ginsenosides on the viability of RAW 264.7 cells (b) and HUVEC cells (c) 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 were presented as the mean ± SD (n = 6). *p < 0.05, vs DMSO group
