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

Clinical evaluation of a novel gallotannin-enriched Galla Rhois extract (GRE) on vital cognitive functions in healthy volunteers: A randomized, double-blind, placebo-controlled study

Functional Foods in Health and Disease, 2023
Background: Oxidative damage has emerged as one of the significant factors in the onset of neurodegenerative disorders, primarily owing to a) higher usage of oxygen by brain cells and b) higher amounts of lipids in the neuronal membranes. Together, these

A radiosensitizer, gallotannin-rich extract from Bouea macrophylla seeds, inhibits radiation-induced epithelial-mesenchymal transition in breast cancer cells

BMC Complementary Medicine and Therapies, 2021
Background Radioresistance can pose a significant obstacle to the effective treatment of breast cancers. Epithelial–mesenchymal transition (EMT) is a critical step in the acquisition of stem cell traits and radioresistance.

Synthesis and Evaluation of Gallotannin Derivatives as Antioxidants and α-Glucosidase Inhibitors.

Chemical and pharmaceutical bulletin, 2021
Gallotannins are phenolic natural products containing galloyl moieties connected to polyhydric alcohol cores, e.g., D-glucose. Some gallotannins are reported to have antidiabetic properties, such as α-glucosidase inhibitory activity.
