(A) Dose response effect of the EOs on the viability of S. cerevisiae cells after 72 h of incubation; (B) Effect of EOs treatment on cellular survival after exposure to H₂O₂. S. cerevisiae cells were pretreated with the essential oils at different concentrations (6.25–100 μg/mL) for 1 h, followed by incubation with H₂O₂ for another hour. Data for 50 and 100 ug/ml were not shown. The data represent the mean of three independent experiments. *P < 0.05, **P < 0.01 and ***P < 0.001, compared with untreated control cells, ^#P < 0.05, ^##P < 0.01 and ^###P < 0.001, compared with cells treated with H₂O₂ only.
