Thiobarbituric acid-reactive substances (TBARS) in vitro. A lipid-rich system was incubated with a free radical source (AAPH) and the effect of different concentrations of EO on the lipoperoxidation was measured by quantifying TBARS. Control is incubation medium without AAPH; other groups contained AAPH alone or in the presence of different concentrations of EO. Trolox was used as standard antioxidant. Bars represent mean ± SEM. aP < .001, when compared to control; bP < .001, when compared to 1 μg/mL; cP < .001, when compared to 10 μg/mL; dP < .001, when compared to 100 μg/mL; eP < .001, when compared to 1 mg/mL. One-way ANOVA followed by Tukey's multiple comparison post hoc test was applied to all data.
