RESUMO
Objective:To study the anti-inflammatory and analgesic effects of different solvent extracts of Folium Pyrrosiae. Meth-ods:Water extract and 75% alcohol extract of Folium Pyrrosiae were obtained. Mouse auricle swelling model induced by xylene was used to observe the anti-inflammation. The analgesic effect was tested by acetic acid writhing test and hot plate test. Results:The eth-anol extract of Folium Pyrrosiae could markedly inhibit the mouse auricle swelling induced by xylene (P<0. 01), and had the ability to inhibit the twisting induced by acetic acid in the mice (P <0. 05). The ethanol extract of Folium Pyrrosiae could increase the threshold of pain in the mice significantly after the 1-hour and 2-hour treatment (P<0. 05). The water extract of Folium Pyrrosiae could inhibit the mouse auricle swelling induced by xylene and the writhing reaction induced by acetic acid (P<0. 05). The water ex-tract of Folium Pyrrosiae could increase the threshold of pain in the mice significantly after the 1-hour treatment (P<0. 05). Conclu-sion:Folium Pyrrosiae has obvious analgesic and anti-inflammatory effects.
