Materials and Methods For evaluating of analgesic and anti-inflammatory activity, we used the carrageenan- and dextran-induced paw oedema, acetic acid-induced writhing, tail flick and formalin pain tests. Results The extract of T. chamaedrys (50-200 mg/kg) and acetylsalicylic acid (100 mg/kg) produced a significant (P< 0.01) inhibition of the second phase response in the formalin pain model, while only the high dose (200 mg/kg) of the extract showed an analgesic effect in the first phase. The extract also inhibited acetic acid-induced abdominal writhes in a dose-dependent manner. The tail flick latency was dose dependently enhanced by the extract but this was significantly (P< 0.05) lower than that produced by morphine (10 mg/kg). The extract (25-250 mg/kg) administered 1 hr before carrageenan-induced paw swelling produced a dose dependent inhibition of the oedema. No effect was observed with the dextran-induced oedema model. Results of the phytochemical screening show the presence of alkaloids, flavonoids and triterpenoids in the extract. Conclusion The data obtained also suggest that the anti-inflammatory and analgesic effects of the extract may be mediated via both peripheral and central mechanisms. The role of alkaloids, flavonoids and triterpenoids will evaluate in future studies. %U https://ijbms.mums.ac.ir/article_5097_b5a0213958eb978d926250db3af2b7bb.pdf
