Figure 1.  Citrus limon essential oil effects on status of lipid peroxidation, nitrite content, and glutathione reduced (GSH) levels in mice hippocampus. Results are mean ± SEM for the number of animals used in experimental procedures. The differences in experimental groups were determined by analysis of variance (ANOVA). ^aP < 0.05 as compared with control animals (ANOVA and Student-Newman-Keuls t-test); ^bP < 0.05 as compared with EO 50 group (ANOVA and Student-Newman-Keuls t-test); and ^cP < 0.05 as compared with EO 100 group (ANOVA and Student-Newman-Keuls t-test).

Figure 2.  Citrus limon essential oil effects on superoxide dismutase, catalase, and glutathione peroxidase activities in mice hippocampus. Results are mean ± SEM for the number of animals used in experimental procedures. The differences in experimental groups were determined by analysis of variance (ANOVA). ^aP < 0.05 as compared with control animals (ANOVA and Student-Newman-Keuls t-test); ^bP < 0.05 as compared with EO 50 group (ANOVA and Student-Newman-Keuls t-test); and ^cP < 0.05 as compared with EO 100 group (ANOVA and Student-Newman-Keuls t-test).
