Special Issue Information

Dear Colleagues,

This special issue meticulously synthesizes contemporary research, unravelling the intricate mechanisms through which antioxidants, present in both foods and natural products, contribute to overall well-being. Operating at molecular and clinical levels, prospective manuscripts offer nuanced insights into the complex interplay between antioxidants and physiological processes, emphasizing the significance of a diet rich in fruits, vegetables, and other nutrient-dense sources.

Beyond conventional paradigms, the collection delves into the absorption, distribution and metabolism of antioxidants and their communication with oxidative-stress-related molecular signalling pathways, elucidating their role in mitigation of pathological processes and disease prevention. The nuanced exploration in preclinical and clinical settings extends to encompass various natural sources materials, broadening the understanding of how antioxidants influence health. Catering to researchers, healthcare professionals, and individuals seeking evidence-based knowledge, this special issue serves as a comprehensive resource, providing a sophisticated perspective on health-enhancing properties of antioxidants in both foods and broader biological contexts. It establishes itself as a valuable reference for navigating the entangled landscape of antioxidant research and its implications for promoting healthy lifestyle in general.

Spinacia oleracea L. cultivar platypus leaves are identified as a functional food due to their nutrient composition which promotes health beyond basic nutrition. Considering the increasing use of food supplements, S. oleracea baby leaves have been extracted by maceration, solid–liquid dynamic extraction (SLDE)-Naviglio, and ultrasound-assisted extraction (UAE) using EtOH and EtOH:H2O mixtures. The analysis of the extracts by using LC-ESI/HRMSMS revealed 42 compounds (flavonoids, polar lipid derivatives, and 20-hydroxyecdysone), along with primary metabolites, detected by NMR analysis. A principal component analysis (PCA) of LC-ESI/HRMS and NMR data was performed, revealing how 20-hydroxyecdysone and flavonoids, the specialized metabolites mainly responsible for the biological activity of S. oleracea leaves, occurred in the highest amount in the EtOH and EtOH:H2O (70:30, v/v) extracts obtained by SLDE-Naviglio extraction. 20-hydroxyecdysone was also quantified in all the extracts via LC-ESI/QTrap/MS/MS using the Multiple Reaction Monitoring (MRM) method. The EtOH extracts obtained by SLDE-Naviglio and maceration showed the highest content (82.16 and 81.27 mg/g extract, respectively). The total phenolic content (118.35–206.60 mg GAE/g), the flavonoid content (10.90–41.05 mg rutin/g), and the Trolox Equivalent Antioxidant Capacity (TEAC) (1.63–2.05 mM) of the extracts were determined. The EtOH:H2O (70:30, v/v) extract analyzed by using SLDE-Naviglio showed the highest phenolic and flavonoid content and radical scavenging activity. Full article
