Antioxidative activity of a cathodic solution produced by the electrolysisof a dilute NaCl solution

The effectiveness was evaluated of a cathodic solution prepared by the elec trolysis of an NaCl solution in inhibiting the aqueous oxidation of ethyl l inoleate and ethyl docosahexaenoate. The decrease in unoxidized substrate a nd the formation of total peroxides during oxidation indicate that the cath odic solution completely inhibited the oxidation of both ethyl esters, whil e these lipids were easily oxidized in an NaCl solution and in distilled wa ter. The antioxidative activity of the cathodic solution was confirmed afte r open incubation for 3 days and 7 days at 37 degrees C, although the scave nging ability of the cathodic solution toward DPPH radicals disappeared dur ing this incubation.
