Karanjin induced cell cycle arrest at G2/M phase in cancer cell lines. a Effect of karanjin in A549 cells as analyzed using flow cytometry. b The percentages of A549 cells at different phases. c Effect of karanjin in HepG2 cells. d The percentages of HepG2 cells at different phases. e Effect of karanjin in HL-60 cells. f The percentages of HL-60 cells at different phases. 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.
