Variation of ROS production of HL60 cells after treatment and analyzed by BD-FACS Caliber flow-cytometer; values are expressed as means ± standard error (n = 3). Ctrl: Control; 5; 10; 20µg/mL. Values affected with different letters are significantly different (p < 0.05) from the control; A isopigarcinol; B epigarcinol; C distribution of ROS fluorescence of isogarcinol and epigarcinol
