Abstract:

Plant polyphenols are becoming more and more popular due to their strong anti-aging properties. The best researched and largest group of polyphenols are flavonoids. Flavonoids have high antioxidant and pharmacological activities and these properties are closely related to their structure. Certain structural elements of these compounds condition their properties and improve or degrade the activities. The polymerization of flavonoids may cause changes in their specific properties. Polymeric flavonoids may exhibit more favourable properties, such as, for example, bactericidal and antioxidant activity. The aim of this study is to polymerize selected flavonoids in reaction with a cross-linking compound. The study analysed the thermal stability of monomeric and polymeric flavonoids and their antioxidant activity. Poly (flavonoids) showed greater resistance to oxidation than their monomeric forms. Polymeric forms of flavonoids obtained in polymerization with a cross-linking compound can potentially be effective thermal stabilizers, e.g. for polymeric materials.
