COMPARAZIONE DEI PROFILI METABOLICI DI VARIETÀ DI CILIEGIO DOLCE (Prunus avium L.) MEDIANTE TECNICHE DI METABOLOMICA UNTARGETED
La diffusione di cultivar altamente produttive ha influito negativamente sulla tutela dell’agro-biodiversità di Prunus avium L. determinando disinteresse nei confronti di varietà meno produttive ma meritevoli di attenzione per il valore delle loro caratteristiche organolettiche e del relativo patrimonio genetico. Il mondo scientifico ha mostrato interesse nei confronti di tale tematica e ha condotto azioni di conservazione in situ ed ex situ per preservare il germoplasma ancora esistente. La presente ricerca analizza l’agrobiodiversità del ciliegio dolce in relazione alla diversa composizione metabolomica dei frutti, espressione del genotipo che le caratterizza. L’attività di ricerca svolta…
Multi-approach metabolomics analysis and artificial simplified phytocomplexes reveal cultivar-dependent synergy between polyphenols and ascorbic acid…

Fruits of the sweet cherry (Prunus avium L.) accumulate a range of antioxidants that can help to prevent cardiovascular disease, inflammation and cancer. We tested the in vitro antioxidant activity of 18 sweet cherry cultivars collected from 12 farms in the protected geographical indication region of Marostica (Vicenza, Italy) during two growing seasons. Multiple targeted and untargeted metabolomics approaches (NMR, LC-MS, HPLC-DAD, HPLC-UV) as well as artificial simplified phytocomplexes representing the cultivars Sandra Tardiva, Sandra and Grace Star were then used to determine whether the total antioxidant activity reflected the additive effects of each compound or resulted from synergis…
The role of mucilage of Opuntia ficus-indica Mill. on sweet cherry fruit during storage
2022
Sweet cherry (Prunus avium L.) is an important crop from temperate areas and is widespread and much appreciated by the consumers when the pedicel is green. The objective of this work was to evaluate the quality of sweet cherry fruit treated with a mucilage coating, extracted from cladodes of Opuntia ficus-indica L. Mill (OFI). The cultivar ‘Ferrovia’ was harvested at the commercial ripeness stage from an orchard in Puglia (Italy), stored for 14 days at 2°C and RH 92% and to evaluated by the variation of color and other qualitative parameters such as physical-chemical, nutraceutical and sensory analysis. Fruits were transferred at 10°C to postharvest laboratory of University of Palermo after…
