摘要：

A new method, rapid and simple to apply, has been developed to measure antioxidant activity. It is based on the electrochemical oxidation of 2,2-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) and gives reliable results, with the monitoring of only absorbance and time. It has been compared with the total antioxidant status test and gives similar but more repeatable results. The method has been applied to wines, brandies and vinegars. It has been confirmed that the antioxidant activity of these products is highly correlated with their polyphenolic. content, and that other majority components in the samples, such as ethanol, SO2 or acetic acid, do not interfere in the method.
