Abstract:

Peripheral analgesic activity of defatted methanol extract of root barks of Capparis spinosa was tested orally at the dose of 100 and 200 mg/kg against pain induced by acetic acid in rats. The dose of 200 mg/kg presents significant analgesic effect with a percentage of inhibition of torsions of 88.51% compared to the positive control which is the acetylsalicylic acid which represents a percentage of inhibition of 92.55%. The dose of 100 mg/kg presents a percentage of inhibition of 81.68%.
