Objective: Mimosa pudica (M. pudica) Linn. (family: Mimosaceae) is a traditionally used folk medicine to treat various ailments including convulsion, alopecia, diarrhea, dysentery, insomnia, tumor, wound, snake bite, etc., Here, the study was aimed to evaluate the potential on antiepileptic, analgesic, and motor activities of M. pudica leaves on rodents. Materials and Methods: In an acute toxicity study, the extracts were administered in doses of 50-2,000 mg/kg/p.o. and behavioral changes were observed for up to 24 h. For a pharmacological study, the ethyl acetate extract of M. pudica (EAMP) leaves in doses of 100 mg/kg/day, 200 mg/kg/day, and 400 mg/kg/day were orally administered for consecutive 7 days to animals. The antiepileptic study was evaluated by inducing electric shock, pentylenetetrazole (PTZ), and isoniazid (INH) in mice, whereas the motor activity test was performed by using an actophotometer, rotarod test, and traction test in mice. The analgesic activity was done by hot-plate, tail flick, and acetic acid-induced writhing in rats. Statistical analysis was carried out by one-way analysis of variance (ANOVA) followed by Dunnett's test. Results: The EAMP showed dose-dependent analgesic activity by increasing the reaction time as compared to the vehicle control. Similarly, the motor performance was improved in dose-dependent manner as compared to standard. The doses (100 mg/kg/day, 200 mg/kg/day, 400 mg/kg/day) of the extract significantly (P < 0.01 and P < 0.001) reduced the duration of seizures induced by maximal electro shock (MES) and delayed the onset of tonic-clonic seizures produced by PTZ and INH. All the tested doses significantly prevented the latency and duration of convulsion against seizure inducers as compared to the vehicle controls. Conclusion: These results revealed that the EAMP possesses potent analgesic, antiepileptic, and motor activities on animals. This could be an effective treatment option for various motor or seizure disorders.
