Karanjin induced apoptosis in cancer cell lines. a Annexin V-FITC/PI staining of A549 cells exposed to karanjin as analyzed by flow cytometry. b Data analyses of A549 cells. c Data analyses of HepG2 cells. d Date analyses of HL-60 cells. Q1 necrosis, Q2 late apoptosis, Q3 early apoptosis, Q4 viable cell. All results are expressed as mean ± SD values from three independent experiments. P value of less than 0.05 (*P < 0.05, **P < 0.01, compared with the control group)are considered significant.
