Abstract : The present work is carried out to study the antioxidant potential of ethanolic extract of Alstonia scholaris Linn. )Apocynaceae( using various in vitro tests including 1, 1-diphenyl-2-picryl-hydrazil )DPPH.( free radical scavenging, metal ion chelating, hydrogen peroxide scavenging, superoxide anion radical scavenging, and ferric thiocyanate reducing ability. Ethanolic extract of Alstonia scholaris had significant )p<0.01( )DPPH.( free radical scavenging )63percent(, metal ion chelating )74.88percent(, hydrogen peroxide scavenging )72.28percent(, superoxide anion radical scavenging )67.66percent( and significant )p<0.05( ferric thiocyanate reducing activities. These various antioxidant activities were compared to standard antioxidants such as butylated hydroxyanisole )BHA(, butylated hydroxy toluene )BHT(, l- ascorbic acid and ?-tocopherol. The results indicated that ethanolic extract of Alstonia scholaris Linn. Possessed antioxidant property. The results observed were comparable to antioxidant properties of BHA, BHT, lascorbic acid and ?-tocopherol.
