ABSTRACT: The proactive kinds of oxygen are produced constantly in human and plants and for example they are by- products of metabolic reactions. Based on Ros proactive oxygen kinds or with attention to Ros kind or proactive oxygen kinds , they are very toxic compositions. Ros cause changing in ceu compositions and damaging to ceu. Ross react to cellular biomolecules severely and they can oxidate every kinds of cellular and vital compositions. This article is about elision of free radicals by herbaceous antioxidants, function mechanism of Ross, special attention to proactive kinds of oxygen and interactions between antioxidants. The most important and effective herbaceous anti oxidants are also discussed.
