Effect of geraniol (25, 50 and 100 mg/kg) in rats submitted to hole-board test. (A) Distance traveled, (B) immobility time, (C) number of rearing and (D) duration of head-dipping. One way ANOVA followed by Fisher's LSD test for multiple comparisons (*p < 0.05, **p < 0.01 and ***p < 0.001 compared with control group; #p < 0.05, ##p < 0.01 and ###p < 0.001 compared with DZP (0.5 mg/kg) group. Data expressed as mean ± SEM. Abbreviations: SLN: saline; DZP: diazepam. Experimental groups: SLN (n = 7), DZP 0.5 mg/kg (n = 7), geraniol 25 (n = 16), 50 (n = 15) and 100 mg/kg (n = 16).
