The anti-inflammatory and analgesic action of the components isolated from some edible plants carried out. We isolated the quercitrin, compound 3 and o-counmaric acid from Cedrela sinensis, Oenanthe javanica and Artemisia princeps var. Orientalis respectively. O-coumaric acid showed the inhibitory effect on carrageenin-induced edema as well as vascular permeability in mice. And we also found the analgesic activity in all compounds isolated from these plants.
