AbstractThe analgesic activity of extracts of Trema guineense (Schum. et Thonn.) Ficalho and Trema micrantha Blume were evaluated in mice by the acetic acid induced writhing test and in rats by the hot plate method. The antiinflammatory and antiarthritic activities were evaluated in rats by the carrageenin‐induced Oedema assay and Newbould's adjuvant arthritis test. Pharmacological activities were compared with indomethacin. The ether and ethanol extracts of both species showed a significant analgesic activity in both tests. As regards the antiinflammatory and antiarthritic activities, the ether extract of Trema micrantha (1 kg of dry leaves) produced the highest percentage of inhibition of carrageenin‐induced oedema and adjuvant arthritis and this effect was comparable to that of indomethacin.
