Summary: Helicobacter pylori (H. pylori) is associated with peptic ulcer disease and gastric cancer. Ellagitannins from chestnut leaves show antibacterial and anti-inflammatory activities, inhibiting IL-8 release and attenuating NF-kappa B signaling in infected cells. These compounds also reduce bacterial growth and cell adhesion, and their bioactivity may be maintained after oral administration.

Summary: The study found that plant extracts rich in proanthocyanidins exhibited different reactivities of procyanidins (PC) and prodelphinidins (PD) during oxidation, with the main reaction route being intramolecular. Additionally, prodelphinidin-rich and galloylated PAs showed significant reductions in PA content during oxidation, accompanied by shifts in the retention times of chromatographic peaks, indicating both intra and intermolecular reactions.

Summary: The addition of chitosan led to a decrease in BSA reactive tannins in all wines, with this effect persisting even after oxidation. Wines previously treated with chitosan and oxidized showed a significant decrease in reactivity towards salivary proteins. Chitosan also resulted in lower formation of polymeric pigments in all wines.

Summary: The research investigates the relationship between the chemical defenses of Quercus ilex leaves and their susceptibility to herbivory, with a focus on the QiMYB-like-1 D165H polymorphism. The study finds that tree clustering based on ecological and genetic factors affects the herbivory index and accumulation of condensed tannins, and demonstrates that condensed tannins may protect Q. ilex from defoliation in Mediterranean ecosystems.

Summary: In this study, 21 oenotannins from different botanical origins were investigated in a model wine solution. The reactivity against proteins and antioxidant properties were found to be influenced by the chemical structure and botanical origin of the oenotannins. The highest turbidity values were observed for gallic hydrolysable tannins. Based on the findings, two formulations were prepared to increase and decrease the oxidation-reduction potential of the model wine.

Summary: Both condensed and hydrolysable tannins have been found to reduce enteric CH4 production in ruminants, but the precise mechanism of action is not fully understood. In this in vitro study, both types of tannins significantly reduced gas and CH4 production, which was primarily attributed to the reduction in digestibility. There was a low direct effect of tannins on rumen microorganisms, but certain bacterial communities showed correlations with tannin inclusion.

Summary: This study investigated the effects of feeding condensed tannin-containing Sericea lespedeza hay on feed intake, digestion, growth performance, energy metabolism, and ruminal fermentation and methane emission in ruminants. The results showed that increasing the concentration of lespedeza in the diet decreased the digestion of fiber and nitrogen, resulting in reduced growth performance. However, the dietary concentration of lespedeza did not affect methane emission in goats or sheep. This suggests that feeding lespedeza has important effects on nitrogen digestion and growth performance in ruminants, but does not decrease methane emission. Further research is needed.

Summary: Tannins are a class of polyphenols with varying degrees of polymerization, which significantly affect their bioavailability and bioactivities. They have been traditionally used in tanning hide to produce leather and are now being recognized for their potential anti-inflammatory, antimicrobial, antioxidant, anticancer, cardiovascular, neuroprotective, and metabolic disease prevention activities. The mechanisms underlying their activity are complex, and further research is needed to fully understand their toxicity.

Summary: Different cowpea genotypes, plant growth stages, and treatments showed variations in polyphenolic content and antioxidant capacity. Immature pods had the highest values, while dry seeds had the lowest. Drought stress led to a slight decrease in some parameters and growth stages, but did not significantly impact the quality of cowpea.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.

Summary: In this study, hollow and solid lignin nanoparticles were synthesized through self-assembly and their application in PVA nanocomposite films was investigated. The results showed that the presence of hollow lignin nanoparticles in the films resulted in a room-like network structure, while the solid lignin nanoparticles induced different structural changes. The inclusion of LNPs improved the mechanical properties of the films, and both types of LNPs exhibited good hydrophobicity.

Summary: This study explored the formation mechanism of agarwood induced by fungus and its potential application in high-quality and high-yielding agarwood production. The results showed that the transition layer played a critical role in the continuous accumulation of agarwood, and the parenchyma cells of the xylem rays and interxylary phloem were the main action site of fungus. The accumulation and distribution of chemical composition in different layers were also investigated. The study identified the drivers of specific compounds and provided a theoretical foundation for future agarwood production.
