Tannin surges increase metal oxide loss and potentially destabilize soil aggregates

Ecotoxicology and Environmental Safety
The unclear mechanisms of interaction between plant-derived tannins and soil metal oxides (Al, Fe, Mn), especially in tannin-rich ecosystems like eucalyptus plantations, hinder accurate predictions of long-term soil health under continuous tannin ...

Ferroptosis-Inhibitory Difference between Chebulagic Acid and Chebulinic Acid Indicates Beneficial Role of HHDP

Molecules, 2021
The search for a safe and effective inhibitor of ferroptosis, a recently described cell death pathway, has attracted increasing interest from scientists. Two hydrolyzable tannins, chebulagic acid and chebulinic acid, were selected for the study.

DNA Breakage by Hydrolyzable Tannins in the Presence of Cupric Ion

Agricultural and Biological Chemistry, 1985
DNA breakage by hydrolyzable tannins of known structures was investigated by agarose or polyacrylamide gel electrophoretic analysis. Hydrolyzable tannins could cause both double-strand and single-strand breakages in λDNA in the presence of Cu2+. The breaking reaction was strongly suppressed at concentrations higher than 100 μm of hydrolyzable tannins ...

Tannin structural elucidation and quantitative31P 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.

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

Food Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...
