Abstract

Aim: The present study evaluated the central and peripheral analgesic activity of methanolic leaf extract of Phoenix sylvestris (PSLME) in swiss albino mice. Method: Peripheral and central analgesic activity was evaluated by tail immersion and acetic acid writhing in swiss albino mice. Dextropropoxyphene was used as a standard drug in the dose of 65mg/kg body weight in both models. PSLME was tested at 100 and 500mg/kg dose level. Results: The result revealed that methanolic extract exhibit 48% and 40.5% writhing inhibition at 500 and 100 mg/kg doses whereas ~30% tail withdrawal reflexes inhibition at 500mg/kg which was analogous to the standard drug dextropropoxyphene. Conclusion: Methanolic extract of leaves of P. sylvestris possesses both peripheral and central analgesic activity in experimental animal.
