Lignin-Hydrolyzable Tannin Interactions in Wood
Journal of Agricultural and Food Chemistry, 1997A series of investigations were carried out to ascertain the relationship between lignin and hydrolyzable tannins in white oak (Quercus alba) and American chestnut (Castanea dentata) milled wood lignins as well as synthetic co-DHPs. Acidolysis and chromatographic analysis of chestnut and white oak milled wood lignins revealed the presence of ellagic ...

Hydrolyzable tannin analysis in food
Food Chemistry, 2012The discovery of plant polyphenols in food is perhaps one of the biggest breakthroughs in modern food science. Plant polyphenols are known for their role in food quality and safety, since they contribute significantly to taste, flavour, colour, stability etc., while they are increasingly recognised as important factors in long-term health, contributing

Hydrolyzed Tannin from Euphorbia glareosa Leaves
Chemistry of Natural Compounds, 2005Hydrolyzed tannin (I), the structure of which was established using chemical investigations and UV, IR, PMR and 13C NMR spectra, was isolated from Euphorbia glareosa leaves.

Phloroglucinol diglycosides accompanying hydrolyzable tannins from Kunzea ambigua
Phytochemistry, 2008Six phloroglucinol diglucosides-kunzeaphlogins A-F (1-6) and a hydrolyzable tannin, kunzeatannin A (7)-were isolated along with 10 known polyphenols from the leaf extract of Kunzea ambigua. Structural elucidation of these compounds was based on spectroscopic analyses and chemical properties.

Anti-inflammatory Hydrolyzable Tannins from Myricaria bracteata
Journal of Natural Products, 2015Twelve hydrolyzable tannins were obtained from the twigs of Myricaria bracteata, including two new hellinoyl-type dimers, bracteatinins D1 (1) and D2 (2); a new hellinoyl-type trimer, bracteatinin T1 (3); two known monomers, nilotinin M4 (4) and 1,3-di-O-galloyl-4,6-O-(aS)-hexahydroxydiphenoyl-β-d-glucose (5); six known dimers, tamarixinin A (6 ...

Combreglutinin, a Hydrolyzable Tannin from Combretum glutinosum
Journal of Natural Products, 1994Combreglutinin [4], a hydrolyzable tannin, was isolated from the leaves of Combretum glutinosum, and its macrocyclic structure was established on the basis of 1 H- and 13 C-nmr and 2D nmr spectroscopic data and by chemical methods. The three known tannins 2,3-(S)-hexahydroxydiphenoyl-D-glucose [1], punicalin [2], and punicalagin [3] were also ...

Hydrolyzable Tannins and Related Polyphenols fromEucalyptus globulus
Journal of Asian Natural Products Research, 2000Eucaglobulin (1), a new complex of gallotannin and monoterpene, was isolated from the leaves of Eucaloptus globulus. Its structure was elucidated on the basis of spectral data. Four known hydrolyzable tannins [tellimagrandin I (2), eucalbanin C (3), 2-O-digalloyl-1,3,4-tri-O-galloyl-beta-D-glucose (4), 6-O-digalloyl-1,2,3-tri-O-galloyl-beta-D-glucose ...

Antinutritional Effects of Condensed and Hydrolyzable Tannins
1992Despite major structural differences, hydrolyzable and condensed tannins often produce similar antinutritional effects. The most common effects are diminished weight gains and lowered efficiency of nutrient utilization. The major biochemical basis for these effects appears not to be inhibition of dietary protein digestion but rather a systemic ...

Preparation of antibodies against hydrolyzable plant tannins
Phytochemical Analysis, 1998Polyclonal antibodies were raised against covalently protein-coupled 1,2,3,4,6-pentagalloylglucose, the common and immediate precursor of the two subclasses of hydrolyzable tannins, i.e. the polyphenolic gallotannins and ellagitannins. The crude antisera were efficiently purified by affinity-chromatography on pentagalloylglucose-substituted Sepharose ...
