Journal of Agricultural and Food Chemistry, 2022 Precipitation of bovine serum albumin (BSA) by 21 hydrolyzable tannins (HTs) and the characteristics of the insoluble complexes were studied stoichiometrically by ultra-performance liquid chromatography. With regard to HT monomers, the protein precipitation and the characteristic of the formed precipitates were unique for each studied HT and depended ...

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

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.

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

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 ...

Immunocytochemical studies on the origin and deposition sites of hydrolyzable tannins
Plant Science, 2001Two specific antibodies, directed toward hydrolyzable tannins, i.e. polygalloylated or oxidized derivatives of 1,2,3,4,6-penta-O-galloylglucose, and toward an acyltransferase from oak leaves that catalyzes the biosynthesis of this principal precursor, were used in immunocytochemical studies to determine the intracellular sites of origin and deposition ...

Hydrolyzable Tannins and Related Polyphenols
1995Recent 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 ...
