Polyphenol Composition, Antioxidant, Antimicrobial and Quorum Quenching Activity of the “Carciofo di Montoro” (<i>Cynara cardunculus</i> var. <i>scolymus</i>) Global Artichoke of the Campania Region, Southern Italy

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.

“…However, G. alata showed a higher polyphenol content compared to Cynara cardunculus var. scolymus (525 GAE μg/g) (Fratianni et al, 2014).…”

Colloidal Gas Aphrons separation to obtain polyphenol rich fractions from artichoke agro-industrial discards

“…Globe artichoke (Cynara scolymus) is a herbaceous perennial plant belonging to the Astaracea family. It is worldwide cultivated and considered one of the greatest sources of antioxidants in the vegetal kingdom (Jiménez-Escrig et al, 2003;Ceccarelli et al, 2010;Ruiz-Cano et al, 2014) as well as presenting a great hypocholesterolemic (Lattanzio et al, 2009;Da Costa et al, 2009;Bekheet, 2011), anticarcinogenic (Shukla & Gupta, 2010;Pereira et al, 2013), antidyspeptic (Marakis et al, 2002), antiseptic and antibiotic activities (Zhu et al, 2004;Gaafar and Salama, 2013;Fratianni et al, 2014) among others. This vegetable is consumed fresh but mainly in its canned form.…”

Metabolomic Fingerprinting of Romaneschi Globe Artichokes by NMR Spectroscopy and Multivariate Data Analysis

“…In a pharmacological analysis of antimicrobial and quorum quenching activity of the extract of the Montoro artichoke, an ecotype also included in our analysis, Fratianni et al () found a good content of polyphenols, among which a high amount of chlorogenic acid and cynarin was detected by ultra‐pressure liquid chromatography (UPLC). Our results are consistent with such findings, with characteristic 1 H‐NMR spectral peaks of these polyphenols (Table ) being recognisable in the spectra of our plant materials.…”

“…Campania is one of the regions in Italy where a large number of landraces is found and genetic characterisation has only recently begun (Rofrano et al , ), while studies on chemical composition are few (Dosi et al , ; Fratianni et al , ) and the comparison of landraces based on metabolic fingerprinting by NMR and chemometrics has not been performed yet.…”
