The aim of the study was to analyze the chemical composition of new artichoke cultivars and hybrids and to assess their potential health-promoting properties. Polyphenols, carotenoids and chlorophylls were identified by liquid chromatography-photodiode detector-mass spectrometry/quadrupole time of flight (LC-PDA-MS/QTof) and quantified by ultra performance liquid chromatography-photodiode detector (UPLC-PDA). Sugar and organic acid profiles were prepared, and antioxidant capacity (ABTS, FRAP and ORAC) and in vitro antidiabetic (inhibition of &alpha:-amylase and &alpha:-glucosidase) and anticholinesterase (inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE)) potentials were evaluated. The analyses revealed a highly varied content of bioactive compounds and great health-promoting potential significantly depending on a cultivar. The content of polyphenolic compounds ranged from 1681.49 (&ldquo:Sambo&rdquo:) to 3638.91 (&ldquo:Symphony&rdquo:) mg/100 g of dry weight (DW). &ldquo:Blanca de Tudela&rdquo: contained the highest amounts of carotenoids and chlorophylls (3761.91 mg/100 g DW) and exhibited high ABTS and ORAC capacity. Inhibition of antidiabetic enzymes was significant in cvs. &ldquo:Symphony&rdquo: and &ldquo:Calico&rdquo:. Additionally, all tested cultivars and hybrids turned out to be effective inhibitors of neurodegenerative enzymes.
