Condensed tannin purification and characterization of tannin-associated proteins
Journal of Agricultural and Food Chemistry, 1980The 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 ...

Tannic acid in concentrations which of themselves have no action potentiates and prolongs the action of adrenaline on the isolated rabbit intestine (inhibitory effect) and on the isolated non-pregnant rabbit uterus (excitatory effect). The adrenaline-pressor effect in the decapitated cat and, in the same species, its stimulant action on the nictitating

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.

Inhibition of Cyanogenesis by tannins
Journal of Chemical Ecology, 1985During isolation of two biosynthetic types of cyanogenic glycosides fromCarica papaya, weak cyanide tests were obtained from initial fractions. Upon final purification, strongly positive cyanide tests were obtained. Pretreatment of extracts to remove polyphenolics alleviated inhibition of cyanogenesis, which led us to suspect that tannins were ...

Behavior of tannins in germanium recovery by tannin process
Hydrometallurgy, 2008Abstract 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.

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.
