Seeds of medicinal plants are common ingredients of many folk and herbal medicines, and seed extracts have been reported topossess pharmacological activity including anti-inflammatory activity. In the present investigation, the methanolic extract of the dried ground seeds of Swietenia mahagoni (SMSE) has been evaluated for anti-inflammatory, analgesic, and antipyretic activities. The anti-inflammatory activity was evaluated using acute, sub-chronic, and chronic models of inflammation in rodents. The antipyretic and analgesic activities were evaluated in mice models. Acute toxicity studies revealed that the extract up to a dose of 1.2 g/kg intraperitoneally was nontoxic. SMSE at doses of 50 and 100 mg/kg, i.p. was found to possess anti-inflammatory, analgesic, and antipyretic activities and the effect was comparable with that produced by the standard drug, ibuprofen. The results of the experiment on arachidonic acid-induced paw edema in rat revealed that the extract produces anti-inflammatory activity through dual inhibition
of the cyclo-oxygenase and lipo-oxygenase pathways of arachidonic acid metabolism. SMSE also enhanced peritoneal cell exudates along with macrophage significantly. The triterpenoids present in SMSE may be responsible for these activities. SMSE possesses antiinflammatory, analgesic, and antipyretic activities.
Key words: Swietenia mahagoni seed, triterpenoids, anti-inflammatory, analgesic, antipyretic effects
