Abstract

Introduction: Marine macroalgae or seaweeds are found in the coastal region have created a promising significance in the biomedical area, mainly because of their contents of bioactive substances. The objective of the present study was to investigate the anticonvulsant activity of chloroform and ethanol extracts of Padina tetrastromatica (PT), a marine macroalgae (brown algae) in mice. Materials and Methods: The anticonvulsant activity of chloroform and ethanol extracts of PT was studied at 400 and 600 mg/kg, against maximal electroshock (MES) and pentylenetetrazole (PTZ) induced convulsion in mice. The duration of tonic hind limb extension (THLE), latency to onset of clonic convulsions and percent protection was noted in MES and PTZ tests, respectively. Phenytoin (25 mg/kg) and phenobarbitone (20 mg/kg) served as reference standards. Results: The chloroform extract of PT at 600 mg/kg significantly decreased the duration of THLE, while ethanol extract did not alter the duration of THLE in MES model. Further, chloroform and ethanol extracts of PT was found to be ineffective as an anticonvulsant when assessed by PTZ-induced convulsive model, as compared to their respective vehicle-treated groups. Conclusion: From the results of the present study it can be concluded that the chloroform extract of PT at 600 mg/kg showed significant anticonvulsant activity, while other extracts lack anticonvulsant activity in MES and PTZ model. However, further studies are required using different animal models to support these findings.

Key words: Anticonvulsant activity, brown algae, maximal electroshock-induced convulsion, Padina tetrastromatica, pentylenetetrazole-induced convulsion
