Abstract

Objective: To study the anti-epileptic effects of methanolic extract of Marsilea quadrifolia Linn. (MQ) in maximal electroshock (MES) and pentylenetetrazole (PTZ) induced rat models of epilepsy. Method: A total of 84 adult male Wistar rats were used. An acute oral toxicity study was conducted on 36 rats and the remaining were used for other experiments. Each model had 24 rats which were allotted into four groups (n¼6). Group I (Control) received 1% carboxymethyl cellulose solution, Group II (Positive control) received phenytoin 300mgkg�1 b.w. in the MES model; sodium valproate 200mgkg�1 b.w. in the PTZ model, Group III (MQ) received 400mgkg�1 b.w. MQ extract and Group IV (MQ) received 600mgkg�1 b.w. MQ extract. Hind limb extension (HLE) time and recovery time were noted in the MES model. Latency for myoclonic jerk, seizures and EEG was recorded in the PTZ model. Results: When compared to control, the phenytoin received group did not show HLE. In MQ pre-treated groups only 50% of rats showed HLE. Sodium valproate and various doses of MQ significantly increased the latency for onset of clonus and seizures. PTZ-induced EEG alterations were significantly attenuated by MQ administration and this was comparable to that of the sodium valproate effect. Conclusion: Marsilea quadrifolia Linn. showed significant anti-epileptic efficacy against various epilepsy models.
