EVALUATION OF ANTICONVULSANT ACTIVITY OF THE LEAVES ETHANOLIC AND AQUEOUS EXTRACTS OF NYCTANTHES ARBORTRISTIS LINN. AGAINST SEIZURES INDUCED BY PENTYLENETETRAZOLE AND ELECTROCONVULSIVE SHOCK IN MICEAbstract
Nyctanthes arbortristis Linn. (Oleaceae) which has been used as an antiepileptic remedy in tribal people of India (Orissa and Bihar) along with its use in Ayurveda, Sidha and Unani systems of medicine was evaluated for anticonvulsant activity against experimental seizures. The leaves ethanolic and aqueous extracts of N. arbortristis protected mice against tonic convulsions induced by maximal electroshock and especially by pentylenetetrazole. Neurotoxicity (sedation and motor impairment) of the extract was assessed by the rota rod test. Preliminary phytochemical analysis showed the presence of alkaloids, tannic acid, flavonoids, iridoid glucosides and Desramnosylverbascoside in the extracts. The acceptable acute toxicity of the extracts recommends further studies to determine the mechanism(s) and compound(s) involved in the anticonvulsant activity.
