ABSTRACT:
The present invention refers to new products generated by the conjugation of flavanols with molecules that contain the thiol group. New molecules are obtained from polyphenolic plant extracts rich in oligomeric and polymeric procyanidines and prodelfinidins. In this way, new products are generated with antioxidant properties for application as protective agents for the organism against disorders such as cancer, cardiovascular diseases and premature aging. The invention also refers to obtaining these new agents from waste material generated by the agroalimentary industry. Since these waste materials are highly complex mixtures a simple and effective method is described to isolate and purify these, based on the physico-chemical characteristics of the new molecules.
