Fig. 1From: Bioactive components and mechanisms of Chinese poplar propolis alleviates oxidized low-density lipoprotein-induced endothelial cells injuryEffects of 8 subfractions separated from ethyl acetate extract of Chinese propolis (EACP) and EACP on cell viability in ox-LDL induced HUVECs injury. a, Effects of the 8 subfractions separated from EACP (2.5 μg/mL) on cell viability in ox-LDL (40 μg/mL) induced HUVECs for 3, 6, 12 and 24 h. b, Effects of the EACP (1.25, 2.5 and 5 μg/mL) on cell viability in ox-LDL induced HUVECs at 3, 6 and 12 h. Cell viability was tested by SRB assay and illustrated in column figures. (*P < 0.05, **P < 0.01 vs ox-LDL group, n = 3). Data are means ± S.E.M.Back to article page
