PHENOLIC CONTENTS AND ANTIOXIDANT ACTIVITY IN CENTRAL-SOUTHERN URUGUAYAN PROPOLIS EXTRACTS

A study on the phenolic content and antioxidant properties of Uruguayan propolis is presented. Identification and quantification was carried out by Reverse Phase High Performance Liquid Chromatography (RP-HPLC). Antioxidant activity was determined by Antiradical Activity Determination (AAD) measured...
