“…As shown in Tables 2–4, the results, averaged across head fractions and season, displayed significant variation among the genotypes for ash and mineral contents (macro‐ and microminerals). Among the macrominerals studied, K was the mineral with a higher concentration, with a global mean content of 18.8 g kg −1 DM (Table 3), as reported in the literature 13, 14, 16, 17. In particular, the highest level was in ‘Blanc Hyerois’ (on average, 25.1 g kg −1 DM), followed by ‘Violetto di Provenza’ and ‘Madrigal F1’, with values of 20.8 and 20.4 g kg −1 DM, respectively.…”

Rincón et al 17 observed that K was the nutrient most absorbed by artichoke plants during the growing cycle. In contrast, Mg and Na were macrominerals having a lower concentration, with a global mean content of 1.5 g kg −1 DM (Table 3).…”

“…Of the former, the most prevalent mineral was K in both the commercial varieties and the new clones, as has been similarly documented elsewhere [2,3,38]. As already reported, K is the nutrient most absorbed by artichoke plants during the growing cycle [39]. On average, the K content of the clones was above that of the commercial varieties (19.6 vs. 17.5 g kg −1 of DM).…”

The globe artichoke is a widely consumed vegetable in the Mediterranean Basin, with Italy being the leading producer. In southern Italy, its cultivation contributes to local economic stability and social development. The producers are increasingly choosing to replace autochthonous varieties, such as 'Violetto di Sicilia', with cultivars bred or selected outside of the region, putting pressure on the maintenance of traditional varieties. Here, we have undertaken a detailed morphological and chemical analysis of a group of clones selected from a population of 'Violetto di Sicilia'. All the traits measured displayed genetic variation, particularly the total content of phenolics and minerals. The capitula of the 'Violetto di Sicilia' clones contained, on average, 6.3 g kg(-1) of fresh weight total phenolics, compared with 4.5 g kg(-1) in the two commercial varieties. The clones also had more inulin than commercial varieties (254 vs. 225 g kg(-1) of dry matter), as well as a good mineral content. The set of clones is of interest in the context of the proposed improvement of the crop through breeding and selection of genotypes with high nutritional quality and a specific end-use (industrial processing or fresh consumption).

“…Our findings are in line with those of Colla et al [7], who reported that potassium was the most abundant macronutrient present in three cultivars of artichoke ('Romolo', Violetto di Provenza' and 'Violetto di Romagna') grown in floating raft culture. The high concentration of potassium in leaf tissue of globe artichoke has been reported earlier by Rincon et al [18] and Pandino et al [19], likely because potassium is the macronutrient most absorbed and translocated to the shoot by artichoke plants. A significant difference among the seven artichoke cultivars was not observed for nitrogen and calcium concentration in leaf tissue, while the levels of phosphorus, potassium and magnesium revealed significant differences (Table 1).…”

Phytochemical Profile, Mineral Content, and Bioactive Compounds in Leaves of Seed-Propagated Artichoke Hybrid Cultivars

The globe artichoke (Cynara cardunculus L. subsp. Scolymus (L.) Hegi) is a multi-year species rich in various classes of phytochemicals with known nutritional and pharmacological properties, such as polyphenols, sesquiterpene lactones, and terpenoids. Over the last decade, hybrids cultivars are transforming the artichoke market for their higher uniformity and stability over the traditional landraces, further increasing the potential of the artichoke as a source of commercial extracts and bioactive molecules. Our aim was to investigate the mineral and phytochemical profiles of leaves from seven seed-propagated hybrids by using an untargeted metabolomic approach based on ultra-high-pressure liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry. Metabolomics identified several compounds in the tested varieties, namely 98 polyphenols, 123 sesquiterpene lactones, and 221 other metabolites. The phenolic content ranged from 3.01 mg Eq./g fw (for ‘Opera’) to 4.71 mg Eq./g fw (for ‘Opal’). Sesquiterpene lactones were, on average, 2.11 mg Eq./g fw. Multivariate statistics (HCA, PCA and OPLS-DA) highlighted the main metabolomics differences among cultivars, which weakly correlated with their agronomic classification. The seven cultivars showed distinctive metabolomics profiles, with ‘Opal’ and ‘Istar’ being the most valuable hybrids. The 3-hydroxyphenyl-valeric acid (a medium-chain fatty acid) and the 6-Gingesulfonic acid (a methoxyphenol) were the most discriminant markers. Our findings illustrated the quantitative and qualitative variation of several classes of phytochemicals in seed-propagated artichoke cultivars and allowed identifying distinctive metabolic signatures for both phenolic compounds and sesquiterpene lactones. This work supports the exploitation of the artichoke leaves from hybrid cultivars as a rich source of bioactive phytochemicals.
