Anti-inflammatory activity of Dalbergia lanceolaria bark ethanol extract in mice and rats.J Ethnopharmacol. 2007 Jun 13; 112(2):300-4.JE
Topical anti-inflammatory activity of Dalbergia lanceolaria Linn. bark ethanol extract was demonstrated in albino mice using TPA-, EPP- and AA-induced ear edema models. The systemic activity of extract was confirmed using acute and sub-acute anti-inflammatory models in albino rats. The ethanol extract exhibited significant systemic anti-inflammatory activity in Carrageenan-induced rat paw edema, by inhibition of histamine and prostaglandin phases of acute inflammation. The extract also showed significant activity against turpentine-induced exudative changes and no activity against granular tissue formation in cotton pellet-induced granuloma in albino rats. Thus, resultant anti-inflammatory activity might be due to effects on several mediators involving cyclo-oxygenase pathway resulting in prostaglandin formation and leukocyte migration from the vessels.
