Identification of the antioxidation reaction products from a sinapic ester in a lipid oxidation system.
As a part of our research project on the elucidation of the chain-breaking antioxidation mechanism for natural phenols in food components, the antioxidation products from a sinapic acid methyl ester in lipid oxidation were identified. Sinapic acid is a potent antioxidative phenolic acid widely distributed in edible plants. The structural determination of the four isolated products revealed them each to have a tricyclic structure consisting of ethyl linoleate, methyl sinapate and molecular oxygen, and these were isomeric compounds for the substituents on the tricyclic moiety.
