<abstract xmlns="http://www.w3.org/1999/xhtml">The aim of this work was to determine the polyphenolic profile and the antibacterial properties of extracts from organic pomegranate peel, to evaluate if it could be used as a potential antimicrobial ingredient to elaborated organic food. The antibacterial properties of different organic pomegranate peel extracts (ethyl acetate, acetone and methanol, with an increasing polarity) were tested against: <italic>Listeria innocua</italic>, <italic>Achromobacter denitrificans</italic> and <italic>Algaligenes faecalis</italic>. All extracts showed antimicrobial activity against all bacteria tested except ethyl acetate extract against <italic>A. denitrificans</italic>. The polyphenolic profile was determined by High Performance Liquid Chromatography (HPLC). Five compounds were identified. Punicagalin was the main component found in acetone and methanol extracts (7,939 µg.g−1 and 5,178 µg.g−1 of lyophilized sample, respectively). Ellagic acid was the main component found in ethyl acetate extract (171 µg.g−1 of lyophilized sample).</abstract>
