Materials and Methods: In this experimental study, 110 male mice were included. Firstly, the maximum non-lethal doses for aqueous and alcoholic extract of Anethum graveolens L. were determined. Three doses of aqueous (250, 400, and 500 mg/kg) and four doses of alcoholic extracts (250, 1000, 2500, and 3500 mg/kg) were intraperitoneally injected 30 minutes before PTZ injection. All doses were lower than the non-lethal dose Seizure stage 1 latency (S1L), seizure stage 5 latency (S5L) and dead time latency (DTL) were recorded after PTZ injection in both control and treatment groups. One-way and two way ANOVA were applied for comparing the results of this study. Results: Aqueous extract of Anethum graveolens L . at 500 mg/kg increased S1L, S5L and DTL significantly (p< 0.01, p< 0.05 and p< 0.01 respectively). Concentration of 400 mg/kg was able to markedly increase only S1L and DTL (p< 0.05 and p< 0.01 respectively) and Concentration or 250 mg/kg had no any effects. Injection of the alcoholic extract at concentrations of 1000, 2500 and 3500 mg increased S1L, S5L and DTL significantly. However, concentration of 250 mg/kg significantly increased only S1L and DTL (p< 0.05 and p< 0.01 respectively). There was no significant between aqueous and alcoholic extract except in DTL. Conclusion: The results indicated that the aqueous and alcoholic extractions of Anethum graveolens L. possibly have protective effects on nervous system and also decrease seizure induced by PTZ.
