CL and PN Induce Cell Apoptosis through Increasing Intracellular ROS Level. (A) Percentage of apoptosis cells were detected with Annexin V/PI staining by flow cytometry analysis. (B) Percentage of intracellular ROS levels were (C) analysed with DCFDA flow cytometry assay. The results are presented as the mean ± standard deviation for n = 3, p < 0.05
