Pharmacology and toxicology of tannins

Archives of Toxicology, 2022
Tannins are an interesting class of polyphenols, characterized, in almost all cases, by a different degree of polymerization, which, inevitably, markedly influences their bioavailability, as well as biochemical and pharmacological activities. They have been used for the process of tanning to transform hides into leather, from which their name derives ...

Interactions of tea tannins and condensed tannins with proteins

Journal of Pharmaceutical and Biomedical Analysis, 2010
Binding parameters for the interactions of four types of tannins: tea catechins, grape seed proanthocyanidins, mimosa 5-deoxy proanthocyanidins, and sorghum procyanidins (mDP=17), with gelatin and bovine serum albumin (BSA) have been determined from isothermal titration calorimetry data. Equilibrium binding constants determined for the interaction with

Saliva tannin interactions

Journal of Oral Rehabilitation, 2000
Many plant foods contain tannins, compounds that bind proteins, such as mammalian enzymes. Although described as tasteless, tannins can be detected orally by their astringency. However, the actual mechanism of oral detection and the effect of tannins on mastication and swallowing have been little investigated.

Behavior of tannins in germanium recovery by tannin process

Hydrometallurgy, 2008
Abstract The behavior of tannins in complexation with various metal ions was investigated to understand the complexation process of germanium, to reduce tannins use, and to improve the germanium recovery as a byproduct in zinc metallurgy. The experimental results obtained show that metal ions with relatively high valence (e.g.

In vitro tannin acantholysis

International Journal of Dermatology, 2000
Abstract Background  Exogenous factors, such as certain drugs, may be involved in the induction of pemphigus. Other offenders sharing a similar chemical composition to these drugs may also play a role. Tannins with their considerable biologic activity were suggested as possible factors.

Condensed tannin purification and characterization of tannin-associated proteins

Journal of Agricultural and Food Chemistry, 1980
The conventional isolation method has been modified in order to minimize protein contamination of tannin purified from high tannin sorghum. The two unique steps of the new procedure are preliminary extraction of the ground grain with ethanol and treatment of the partially purified tannin with phenol to remove traces of noncovalently bound protein ...
