Flavone, its various methoxy derivatives and flavanone were investigated for their anti-inflammatory activity in carrageenin- induced paw edema in mice (acute) and cotton pellet granuloma in rats (chronic). In the acute study flavone,3,6,7, and 2,-methoxy flavones exhibited a dose related anti-inflammatory activity. However, compounds like flavanone, 5-and4'-methoxy flavones failed to show any anti-inflammatory response. In the chronic model, almost all the compounds except 4' - methoxy flavone exerted dose related anti-inflammatory effect. Thus a definite structure activity relationship could be observed in the anti-inflammatory activity of these compounds.PDF
