Introduction: A relationship between epileptic seizures and brain tissue oxidative damage has been suggested. Ocimum basilicum (O. basilicum) has been suggested to have beneficial effects including hypnotic protective agains tissue oxidative damage. The present study was designed to evaluate the effects of hydro-alcoholic extract of O. basilicum on oxidative damage of brain tissue following seizures induced by pentylenetetrazole (PTZ) in mice.

Methods. The animals were grouped and treated as follows: 1- control group which recived saline, 2- PTZ group (90 mg/kg, i.p.), 3-5- three groups which received  25, 50 or 100 mg/kg of a  hydro-ethanolic extract of O. basilicum before PTZ. MCS (first minimal clonic seizure) and GTCS (the first generalized tonic-clonic seizure) latencies were analyzed. The brains of the animals were then collected and stored to use for biochemical evaluation.

 Results. The plant extract in 50 and 100 mg/kg doses, significantly postponed the MCS and GTCS seizures onsets (P<0.05-P<0.01) when administered before PTZ. PTZ - induced seizures also increased lipid-peroxidation in the brain tissue which was presented by a high level of malondialdehyde (MDA) in the brain tissue compared to the control group(P<0.001). O. basilicum extract attenuated  MDA levels in the brain (P<0.05-P<0.001). PTZ - induced seizures also decreased brain tissue total thiols compared to the control group(P<0.001). Pretreatment with all doses of O. basilicum extract improved thiol content in the brain tissue (P<0.05).

 Conclusions. The current study revealed that hydro-ethanolic extract of O. basilicum possesses significant antioxidant and anticonvulsant activities.
