抄録

Study was made on separating and confirming various antioxidants rapidly by the application of electrophoresis. <br>The majority of the antioxidants are difficultly soluble in water and do not ionize as they are but when coupled with diazonium salt of sulfanilic acid and made into azo-dyes, each will show its characteristic color, depending on the kind of antioxidants and at the same time, will become ionized. It will become possible to detect the different kinds of antioxidants when electrophoresis is carried on with these azo-dyes. That is, paper electrophoresis was carried on by coupling acetic acid solution of amine antioxidants with diazonium salt dissolved in acetic acid using acidic electrolyte (acetic acid-isopropanol-water mixture). Also, phenolic antioxidants dissolved in ethanolic sodium hydroxide solution was coupled with diazonium salt and then electrophoresis carried on with aqueous borax solution or methanolic solution or ethanolic solution of borax as electrolyte. The various antioxidants were easily detected by observing the movement of substances on the filter paper and by the characteristic coloring after electric current was passed for an appropriate time.
