The GSH levels are increased in HepG2 cells treated with rosemary essential oil. (A) The intracellular GSH levels of HepG2 cells incubated with 0.01% rosemary essential oil for 1, 6 and 12 h. Data values are expressed as a percentage of the untreated control, which was set at 100%. Results are the mean±SEM (n=3). bP<0.05 vs untreated cells. (B) The intracellular GSH levels of HepG2 cells incubated with the indicated doses of rosemary essential oil for 12 h. (C) Cell viability of HepG2 cells incubated with 0.005% and 0.01% rosemary essential oil for 24 h. Data are expressed as the mean±SEM of three independent experiments. No significant differences were found by ANOVA.
