Analgesic Activity of Tragia involucrata

Abstract

The work was carried out to investigate the analgesic activity of the whole plant of Tragia involucrata Linn. The dried whole plant was successively extracted with petroleum ether, ethyl acetate and methanol. Experiments were carried out with these extracts for their peripheral and central antinociceptive potentials on acetic acid induced writhing and radiant heat tail-flick models in mice, respectively. Both the ethyl acetate and methanolic extracts showed significant writhing inhibition while the elongation of tail-flick time was most prominent with methanolic extract at an oral dose of 500 mg/kg body weight. Key words: Tragia involucrata, Analgesic activity, Acetic acid induced writhing, Radiant heat tail-flick. Dhaka Univ. J. Pharm. Sci.
