Figure 9: Kalanchoe blossfeldiana extract induced the production of ROS in human cervical carcinoma cells. The cells were incubated with 0.5% dimethyl sulfoxide (a) as the control and the extract at concentrations of 2.0, 5.0 (b), 10.0, 20.0 (c), 50.0 (d) and 100.0 μg/mL (e) for 24 h. The level of reactive oxygen species production in the cells was estimated in comparison to the control (dimethyl sulfoxide) (f). Each sample was run in triplicate. Error bars represent standard deviations. Significant differences relative to the control are marked with an asterisk “*” (P < 0.05)
