Abstract : Method of screening a mixture of organic compounds to detect the presence of an antioxidant material wherein the organic mixture is first chromatographically separated on a polyamide coated plate and then coated with linoleic acid. The plate is heated until the linoleic acid oxidation products react with the free amine groups on the polyamide material to produce a color change. Antioxidant compounds separated on the plate inhibit the color change and can be visually detected. (Author)
