Representative cytograms of the flow cytometric analysis of ALDH⁺ populations. The ALDH⁺ population of JIMT-1 cells evaluated after 72 h of treatment with the fractions. SO, aqueous fraction of S. oxyacanthum (69 μg/mL). CS, chloroform fraction of C. simensis (80 μg/mL). VL, ethyl acetate fraction of V. leopoldi (0.87 μg/mL). FL1-H, green fluorescence signal - height. SSC-A, side scatter signal – area. The percentage shows the percent of total cells in the area delineated with red which defines the ALDH positive cells
