Globe artichoke (Cynara scolymus L.) is a typical vegetable of the countries of the Mediterranean basin. It produces edible immature flower bud and his cultivation has a great economic importance in Italy, first world producer. In the recent years, local cultivars have been gradually replaced with the modern ones, mostly due to the increasing demand of early products for the large-scale retail trade. The valorization of local resources, such as specific cultivars useful in productive processes, may contrast this tendency. In this framework, the aim of this research is the nutritional and metabolic characterization of the Cynara scolymus L. cv Capuanella, a typical artichoke of the Campania Region. The nutritional profile (i.e. moisture content, dietary fiber, ash, total proteins, lipids and carbohydrates, total and free amino acids, fatty acid composition, folic acid, C vitamin, total phenolic compounds) of edible immature flower bud of globe artichoke cv Capuanella was determined and compared to the Italian artichoke nutritional profile reported in the National Institute of Research on Food and Nutrition (INRAN) tables. On a fresh weight basis, the Capuanella artichoke total protein content was higher in comparison with the INRAN tables (3.08 vs. 2.70g/100 g, respectively), whereas essential amino acids were lower in Capuanella with respect to the INRAN values (826.3 vs. 884 mg/100 g, respectively). Among the fatty acids of Capuanella artichoke, the most abundant were the essential n-6 linoleic (55.20 mg/100 g) and palmitic (34.80 mg/g) acids, representing about 72% of the total fatty acids. Ascorbic acid was 13.70 mg/100 g, while folic acid represents 17% of Recommended Dietary Allowance (65.00 μg/100 g). Phenolic compounds were found to be abundant in Capuanella artichoke (1878.21 mg/100 g); in particular, the chlorogenic acid (425.46 mg/100 g) represents about 23% of total phenolic compounds. Finally, as confirmed by the AFLP analysis, the Capuanella artichokes belong to the "Romanesco" group.

Abstract
Globe artichoke (Cynara scolymus L.) is a typical vegetable of the countries of the Mediterranean basin. It produces edible immature flower bud and his cultivation has a great economic importance in Italy, first world producer. In the recent years, local cultivars have been gradually replaced with the modern ones, mostly due to the increasing demand of early products for the large-scale retail trade. The valorization of local resources, such as specific cultivars useful in productive processes, may contrast this tendency. In this framework, the aim of this research is the nutritional and metabolic characterization of the Cynara scolymus L. cv Capuanella, a typical artichoke of the Campania Region. The nutritional profile (i.e. moisture content, dietary fiber, ash, total proteins, lipids and carbohydrates, total and free amino acids, fatty acid composition, folic acid, C vitamin, total phenolic compounds) of edible immature flower bud of globe artichoke cv Capuanella was determined and compared to the Italian artichoke nutritional profile reported in the National Institute of Research on Food and Nutrition (INRAN) tables. On a fresh weight basis, the Capuanella artichoke total protein content was higher in comparison with the INRAN tables (3.08 vs. 2.70g/100 g, respectively), whereas essential amino acids were lower in Capuanella with respect to the INRAN values (826.3 vs. 884 mg/100 g, respectively). Among the fatty acids of Capuanella artichoke, the most abundant were the essential n-6 linoleic (55.20 mg/100 g) and palmitic (34.80 mg/g) acids, representing about 72% of the total fatty acids. Ascorbic acid was 13.70 mg/100 g, while folic acid represents 17% of Recommended Dietary Allowance (65.00 μg/100 g). Phenolic compounds were found to be abundant in Capuanella artichoke (1878.21 mg/100 g); in particular, the chlorogenic acid (425.46 mg/100 g) represents about 23% of total phenolic compounds. Finally, as confirmed by the AFLP analysis, the Capuanella artichokes belong to the "Romanesco" group.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
