(A) Cytotoxic activity of various concentrations of CL on MDAMB-231 cells after 24 h; (B) induction of ROS level by CL treatment on MDAMB-231 breast cancer cells, the ROS level of cells exposed to CL individually for 24 h was measured by flow cytometry after staining with 2ʹ, 7ʹ-dichlorofluorescein diacetate; (C) the % level of ROS. Data are presented as mean + SEM, N = 3. *P < 0.05 Indicates significant differences in comparison with the untreated cells. CL, Curcuma longa; ROS, reactive oxygen species.
