Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Tannin Structural Elucidation and Quantitative P-31 NMR Analysis. 1. Model Compounds [PDF]

, 2013
Tannins and flavonoids are secondary metabolites of plants that display a wide array of biological activities. This peculiarity is related to the inhibition of extracellular enzymes that occurs through the complexation of peptides by tannins.

The Evolving Therapeutic Landscape of Gallic Acid: A Review of Mechanistic Insights and Clinical Potential

Molecular Nutrition &Food Research, Volume 70, Issue 9, 13 May 2026.
ABSTRACT Gallic acid (GA), a plant‐derived phenolic compound, is evolving from a general antioxidant into a specific molecular modulator and a functional building block for advanced biomedical materials. This review synthesizes recent insights underpinned by GA's “redox duality”—its capacity to act as either a radical scavenger or a pro‐oxidant.

Characterization of 20 Oenological Tannins from Different Botanical Origins for Formulation of Blends with Redox Potential Tuning Ability in Model Wine Solution

Antioxidants, 2023
Twenty oenotannins from different botanical origins were studied in model wine solution (1 g/L, 12% ethanol, pH 3.5). An original device was created for measuring Oxidation–Reduction potential (ORp) of the solutions at 20 °C in strict anoxic condition by
