Combreglutinin, a Hydrolyzable Tannin from Combretum glutinosum

Journal of Natural Products, 1994
Combreglutinin [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 ...

Dietary Intake of Hydrolyzable Tannins and Condensed Tannins to Regulate Lipid Metabolism

Mini-Reviews in Medicinal Chemistry, 2022
Abstract: Lipid metabolism disorder is a multifactor issue, which contributes to several serious health consequences, such as obesity, hyperlipidemia, atherosclerosis diabetes, non-alcoholic fatty liver, etc. Tannins, applied as naturally derived plants, are commonly used in the study of lipid metabolism disease with excellent safety and effectiveness

Biosynthesis and subcellular distribution of hydrolyzable tannins

Phytochemistry, 2001
Pathways to complex gallotannins have been elucidated by enzyme studies, indicating that beta-glucogallin is required as principal acyl donor. Evidence for the in vitro oxidation of pentagalloylglucose, the pivotal metabolite in this sequence, to ellagitannins, is presented. Immunohistochemical studies with antibodies raised against pentagalloylglucose

Chemical Studies of Proanthocyanidins and Hydrolyzable Tannins

Antioxidants & Redox Signaling, 2001
We investigated a number of natural polyphenols representing flavan-3-ols, gallotannins, and ellagitannins with regard to their antioxidant potential. For this purpose we used pulse radiolysis to determine scavenging rate constants with hydroxyl radicals and decay rates of the respective aroxyl radicals and EPR spectroscopy to identify the radicals ...

Hydrolyzable Tannins and Related Polyphenols

1995
Recent advances in isolation and structure elucidation of several hundred of new polyphenolic compounds of the tannin class using new techniques (1) have altered the definition of a tannin, at least that of a hydrolyzable tannin. Thus the term tannin now includes all polyphenolic compounds of defined chemical structure as well as the whole group of ...

Hydrolyzable tannin analysis in food

Food Chemistry, 2012
The 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
