Oxidative stress assay in vitro. A: Electron spin resonance (ESR) spectroscopy performed 30 min after linalool treatment. The signal intensity of 1:2:2:1 suggests generation of hydroxyl radical, the strongest reactive oxygen species (ROS); B: The signal of HCT 116 without linalool at the same time period; C: Diphenyl-1-pyrenylphosphine (DPPP) assay performed to detect lipid peroxidation showed that linalool induced cell membrane lipid peroxidation as green fluorescent on the cell surface(white arrow); D: The cell membrane lipid peroxidation was not observed in without linalool treatment group.
