  ABSTRACT: Biochemical characteristics, antimicrobial and quorum quenching activity of the extract of the “Carciofo di Montoro”, a typical ecotype of Cynara cardunculus var. scolymus of the Campania region (Southern Italy) were studied, to consider it as potential reserve of bioactive constituents useful for food industry and beneficial for managing and preventing several chronic illnesses in humans. The extract exhibited a good polyphenol content (528 μg GAE/g) and antioxidant activity (EC50 less than 5 mg). Ultra pressure liquid chromatography (UPLC) revealed high amount of chlorogenic acid, cynarin and epicatechin. The extract showed antimicrobial activity against Escherichia coli, Staphylocccus aureus, Pseudomonas aeruginosa, Enterococcus faecalis and Bacillus cereus pathogen strains. Finally, quorum quenching activity was demonstrated. The variety Carciofo di Montoro could represent a good source of health-promoting polyphenols, encouraging a nutraceutical use of such ecotype, for several phyto-pharmaceutical applications.
