Powdered Hide Model for Vegetable Tanning II: Hydrolyzable Tanni [PDF]

, 2015
Vegetable tannages employ both condensed and hydrolyzable tannins. As part of our exploration of tanning mechanisms, we reported previously on interactions of the condensed tannin, quebracho, with powdered hide.

Separation and purification of hydrolyzable tannin from Geranium wilfordii Maxim by reversed-phase and normal-phase highspeed counter-current chromatography

, 2010
Three hydrolyzable tannins, geraniin, corilagin and gallic acid, main active components of Geranium wilfordii Maxim, have been separated and purified in one-step by both reversed-phase and normal-phase high-speed counter-current chromatography.

Comprehensive Characterization of Acer truncatum Leaf Extract: Identification of Systemic Metabolites and Effects on Performance, Antioxidant Status, and Intestinal Microbiota in Laying Hens

Animal Research and One Health, EarlyView.
Dietary A. truncatum leaf extract is absorbed and improves laying performance in aged hens by enhancing systemic antioxidant capacity and modulating the gut microbiota. ABSTRACT The demand for natural feed additives is considerably increasing in the antibiotic‐free feed era.

Two New Phenolic Constituents from the Stems of Euphorbia griffithii

Natural Products and Bioprospecting, 2019
Phytochemical studies on MeOH extract of stems of Euphorbia griffithii led to the isolation of one new hydrolyzable tannin dimer, corilagiffithiin (1) and one new galloyl-glucoside (2), alongside six known ones (3–8).

Perspectives in biomedicine: Superfoods and antioxidant power classification

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The market value of natural food antioxidants will double to 8 billion USD by 2033, driven by a global consumer demand for ‘clean label’ products and proactive wellness solutions. However, the industrial application and health labelling (commercial brands) of these compounds remain severely constrained by inconsistent analytical methods.

Condensed and Hydrolyzable Tannins for Reducing Methane and Nitrous Oxide Emissions in Dairy Manure—A Laboratory Incubation Study

Animals, 2022
The objectives of this study were to (1) examine the effects of plant condensed (CT) and hydrolyzable tannin (HT) extracts on CH4 and N2O emissions; (2) identify the reactions responsible for manure-derived GHG emissions, and (3) examine accompanying ...

Hydrolyzable tannin structures influence relative globular and random coil protein binding strengths

, 2007
Binding parameters for the interactions of pentagalloyl glucose (PGG) and four hydrolyzable tannins (representing gallotannins and ellagitannins) with gelatin and bovine serum albumin (BSA) have been determined from isothermal titration calorimetry data.

Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.

Solid-State Fermentation of Sorghum by Aspergillus oryzae and Aspergillus niger: Effects on Tannin Content, Phenolic Profile, and Antioxidant Activity

Foods, 2022
Sorghum contains antioxidants such as tannins. However, these are considered antinutritional factors since they are responsible for the low digestibility of proteins and carbohydrates. Nevertheless, these can be extracted by solid-state fermentation (SSF)
