In Thai floklore medicine, gamboge, the yellow gum-resin secreted from Garcinia hanburyi, is used for infected wound, pain and edema The ethyl acetate extract from Garcinia hanburyi (GH5763) was assessed for anti-inflammatory, analgesic and antipyretic activities using experimental animal models. It was found that GH5763 possessed inhibitory activity on acute phase of inflammation as seen in ethyl phenylpropiolate-induced ear edema and carrageenin-induced hind paw edema in rats. However, GH5763 did not elicit any inhibitory effect on arachidonic acid-induced hind paw edema. In subchronic inflammatory model, GH5763 provoked a significant reduction of both transudative and proliferative phase when tested on cotton pellet-induced granuloma model. GH5763 also reduced the alkaline phosphatase activity in serum of rats in this animal model. In the analgesic test, GH5763 elicited inhibitory activity on acetic acid-induced writhing response and on both the early and the late phase of formalin test. Moreover, GH5763 also possessed an excellent antipyretic effect when tested in yeast-induced hyperthermic rats. It is postulated that the anti-inflammatory, analgesic and antipyretic activities of GH5763 are caused by the inhibition of the prostaglandin biosynthesis. © 2007.
