The medicinal plants have been selected for thorough studies from indig-enous folk medicines, Ayurvedic, Unani and Siddha systems of medicines. The aim of this study deals with the comparative evaluation of anti-inflammatory activity of the bark of Ficus bengalensis in plants of different age. The anti-inflammatory activity was evaluated by rat paw edema model induced by carrageenan for acute inflammation and cotton pellet granuloma model for chronic inflammation. Indomethacin was used as a standard drug. The various extracts were studied for their anti-inflammatory activity in carrageenan-induced hind paw edema in rats and the paw volume was measured plethysmometrically from 0 to 3h after injection. We have determined the anti-inflam-matory activity of various extracts of the bark of Ficus bengalensis with oral adminis-tration doses of 300 and 600 mg/kg/day of body weight to healthy animals. Positive results for flavonoids, sterols, and triterpene, tannins and saponins compounds were in-vestigated by phytochemical analysis. The ethanolic extract of younger plant showed a greater anti-inflammatory effect compared with the standard drug indomethacin. Present studies besides confirming anti-inflammatory activity of the ethanolic extract of younger more potent than mature plant help to identify from the comparative study of the bark of Ficus bengalensis.
