We aim to assess the anticonvulsant potential of Ajuga bracteosa Wall. The aqueous methanol extract (30:70) of Ajuga bracteosa and its n-hexane, chloroform and ethyl acetate fractions were prepared. Anticonvulsant effect was evaluated using different animal models of epilepsy. Crude extract along with its fractions at 500 and 1000 mg/kg doses, administered orally to albino mice were appraised against pentylenetetrazole-induced, strychnine-induced and picrotoxin-induced convulsions. Moreover, effect of test substances on brain GABA level and phenobarbitone induced hypnosis was also studied at dose level of 350 and 400 mg/kg. The plant extract and its fractions produced potent dose dependent anticonvulsant activity in all models of epilepsy. In addition, plant extract and fractions increased brain GABA level and potentiated phenobarbitone-induced sleep duration. From the results it can be deduced that Ajuga bracteosa possess potent anticonvulsant activity, supporting its folkloric use in the treatment of epilepsy.
