ABSTRACT

Boswellia dalzielii (Burseraceae) has been used in folkloric medicine to treat diseases related to inflammation. The present work was aimed to access the acute and chronic anti-inflammatory effects of the ethanol extract of the resin of B. dalzielii (EERBD) in mice. The anti-inflammatory effect was evaluated in three experimental models: Doses of 100, 200 and 400 mg/kg of EERBD were administered orally in carrageenan-induced rat hind paw oedema, xylene-induced ear oedema in mice, and cotton pellet-induced granuloma formation), using dexamethasone 1 mg/kg as standard drugs in mice. Phytochemical analysis indicated that the EERBD contains pharmacological compound, namely: polyphenol, tannins, reducting sugars, alkaloids, saponins, sterols, and triterpènes. Results obtained showed that The EERBD possessed a significant (p < 0.001) anti-inflammatory activity which compared with the negatif control at the first hour with 83.39%, 74.19%, 85.74% and 88.99% respectively, as a percentage inhibition for the 100, 200 and 400 mg /kg. On the other hand, in the xylene induced edema test, the extract at the same doses, also exhibited an anti-inflammatory activity. The ethanol extract of resins of B. dalzielii Hutch, in a 7-day study, daily administration of B. dalzielii suppressed cotton pallet-induced rat granuloma formation. These results might be suggested that B. dalzielii can be used as anti-inflammatory medicine.
