Figure 1: Effect of Allium cepa L. on cell proliferation on RAW 264.7 cells. Cells were cultured in the presence of AcE (10–8000 μg/mL); untreated cells (Ctrl) were not exposed to AcE; and DMSO was used for positive control. After 5 days of continuous exposure, cell proliferation was assessed using Alamar blue assay. The columns represent the mean values of the results obtained of three independent experiments. There was no significance between negative control (Ctrl) and cells in all concentrations tested. There was significance between positive control (DMSO) and cells in all concentrations tested ANOVA-Tukey.
