Evaluation of anti-inflammatory activity of Alstonia macrophylla Wall ex A. DC. leaf extract.
Methanolic extract of dried leaves of Alstonia macrophylla Wall ex A. DC. and its fractions were investigated for its anti-inflammatory activity. The extract at a concentration of 200 mg kg(-1) and 400 mg kg(-1), p.o. and its fractions at 25 mg kg(-1) and 50 mg kg(-1), p.o. showed the significant dose dependent antiinflammatory activity in carrageenan and dextran-induced rats hind paw edema (acute models) as well as in cotton pellet-induced granuloma (chronic model) in rats. Anti-inflammatory activity of the tested extract and its fractions was comparable with that of the standard drug Indomethacin (10 mg kg(-1)).
