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

Correlation of oxidative transformations of hydrolyzable tannins and plant evolution
Phytochemistry, 2000The progressive oxidative transformations in the biogenesis of hydrolyzable tannins, gallotannin (I) --> ellagitannin (II) --> dehydro ellagitannin (III) --> transformed dehydroellagitannin (IV), conform in several aspects to the evolutionary routes in the subclasses of Dicotyledonae, particularly in the Rosidae.

Dietary Intake of Hydrolyzable Tannins and Condensed Tannins to Regulate Lipid Metabolism
Mini-Reviews in Medicinal Chemistry, 2022Abstract: 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

Oligomeric hydrolyzable tannins from Monochaetum multiflorum
Phytochemistry, 2004Four hydrolyzable tannins, nobotanins Q, R, S, and T, were isolated from the aqueous acetone extract of the dried leaves of Monochaetum multiflorum (Melastomataceae), a plant indigenous to Colombia. Their dimeric and tetrameric structures were elucidated by spectral and chemical methods.

Hydrolyzed Tannins from Geranium pusillum
Chemistry of Natural Compounds, 2003The polyphenolic compound 1-O-galloyl-3,6-hexahydroxybiphenyl-D-galactopyranoside (pusilagin) was isolated from the aerial part. The tannin structure was established using acid hydrolysis and IR, PMR, and 13C NMR spectral methods.

Chemical Studies of Proanthocyanidins and Hydrolyzable Tannins
Antioxidants & Redox Signaling, 2001We 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 ...

Biosynthesis and subcellular distribution of hydrolyzable tannins
Phytochemistry, 2001Pathways 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
