Natural Compounds with Antioxidant Properties

Abstract:

Article Preview

Natural substances with polyphenolic structure exhibit remarkable antioxidant properties, being widely used in preventing various diseases. Among these, the oenotanins obtained from grapes seeds are proantocianidinic compounds with high molecular mass, water insoluble and as a result, rather difficult to be utilized. The aim of this paper was to produce their hydrosolubilization and the structure of the product resulted (enoxyl) has been investigated by MS, IR, UV-Vis spectroscopy. The antioxidant activity of oenotanins and enoxyl has been quantified by chemiluminescence technique, and the minimum concentration able to capture completely the free radicals has been also established.
