“…Our study was meant to identify all possible phytoconstituents with the used experimental setup, and as a consequence 49 and 51 molecules were described in the aqueous and hydro-alcoholic artichoke extracts, respectively. Some of the newly identified compounds were confirmed by standards, while other compounds have already been reported by others [15][16][17][18][19][20][21][22][23][24][25][26].…”

Comparative Chemomapping of Phytoconstituents from Different Extracts of Globe Artichoke - Cynara Scolymus L.

ABSTRACT. Artichoke (Cynara scolymus L.) is a well-known herb for its efficiency in the prevention/treatment of liver injuries, among other human chronic diseases. The aim of present study was to analyse the phytoconstituents content of aqueous and hydro-alcoholic extracts obtained from the leaves of artichoke. The chemomapping was carried out using UHPLC-ESI-MS. Several new and some known phytoconstituents were identified in the two type of extracts that have slightly different composition profiles. The newly found phytoconstituents in artichoke, plead for multiple health promoting effects that have presumably more stochastic than determinative features. Therefore, further experiments are needed using such extracts, and based on a system biology approach to clarify the complexity of beneficial effects of artichoke.

“…The values measured for antioxidant capacity were generally lower than those observed for other artichoke varieties, like "Violetto di Chioggia" and "Violetto di S. Erasmo" [2]; if we consider "Violetto di Toscana", instead "Violet d'Hyères", the total antioxidant capacity (TAC) values are on average 50% higher. This variability in the concentration of antioxidant compounds is mainly due to genetic aspects, agronomic practices, and environmental conditions [1,40]. Furthermore, the high content of antioxidants and total phenols in T0 and T1 may also be connected to more stressful conditions that the plant cuttings have experienced before transplanting in the experimental field.…”

Effect of Vegetative Propagation Materials on Globe Artichoke Production in Semi-Arid Developing Countries: Agronomic, Marketable and Qualitative Traits

et al. 2017

Abstract:In Tunisia, globe artichoke is mainly propagated by underground dormant axillary buds (ovoli), which are removed from the field in August during the quiescence period. The high cost of in vitro-plants and the absence of specialized nurseries were among the reasons for the rise of heterogeneity and spread of diseases. The aim was to help farmers to improve artichoke yield and quality by ameliorating their vegetative propagation technique with low cost methods. Three plant cuttings management methods were tested: summer ovoli (T0); spring offshoots nursery's cuttings forced to pass a vegetative rest period by stopping irrigation (T1); and offshoots nursery's cuttings not forced (T2). The cuttings management can affect both yield and qualitative traits of artichoke. T1 nursery plants produced the heaviest primary heads, 7% and 23% higher than T2 and T0, respectively. T1 plants exhibited the highest yield during the harvest season, with +17.7% and +12.2% compared to T0 and T2, respectively. T0 and T1 showed the highest total antioxidant capacity and inulin content; the propagation method also affected the short-chain sugars ratio. T1 is a viable and sustainable alternative to the traditional one that does not heavily impact on growing costs and improves yield and quality of artichoke.

“…Despite the many articles reporting the phenolic composition of artichoke hydroalcoholic extracts, 13,15,16,[31][32][33][34][35][36][37][38][39][40] the present work characterizes the phenolic composition in infusions. Moreover, infusion is the most common form to consume this plant and, to our knowledge, this is also the first report presenting results for the whole plant material and not seeds.…”

“…41 Dicaffeoylquinic acids have been extensively reported in Table 2 Retention time (Rt), wavelengths of maximum absorption in the visible region (λ max ), mass spectral data, identification and quantification of phenolic compounds in hydromethanolic extract and infusion of milk thistle (mean ± SD) a hydroalcoholic extracts obtained from different parts of artichoke, as mentioned above. 13,15,16,[31][32][33][34][35][36][38][39][40] Four signals in artichoke (compounds 4, 9, 11 and 13) showed a pseudomolecular ion ([M − H] − ) at m/z 337 (Tables 1 and 2). These compounds were assigned as the 3-acyl, 4-acyl and 5-acyl isomers of p-coumaroylquinic acid based on their HPLC retention and MS 2 fragmentation characteristics, as previously reported by Clifford et al 29,42 Thus, compound 4 (artichoke) was tentatively identified as 3-p-coumaroylquinic acid, yielding the base peak at m/z 163 ([coumaric acid-H] − ).…”

Cynara scolymus L. (artichoke) and Silybum marianum (L.) Gaertn (milk thistle) are two herbs well-known for their efficiency in the prevention/treatment of liver injuries, among other chronic diseases. Therefore, the aim of this work was to characterize specific bioactive components, phenolic compounds, in hydromethanolic extracts but also in infusions (the most commonly used preparations) obtained from the whole plant of milk thistle and artichoke. The phenolic profiles were accessed using HPLC-DAD-MS/ESI. Infusions of both species presented higher phenolic contents than the hydromethanolic extracts. Milk thistle presented a similar phenolic composition between the two preparations, revealing only differences in the quantities obtained. Nevertheless, artichoke revealed a slightly different profile considering infusion and hydromethanolic extracts. Apigenin-7-O-glucuronide was the major flavonoid found in milk thistle, while luteolin-7-O-glucuronide was the most abundant in artichoke. Therefore, infusions of both artichoke and milk thistle represent a good source of bioactive compounds, especially phenolic acids and flavonoids.
