متن کاملInteractions of Condensed Tannins with Selected Proteins
The relative affinities ufeondensed tannins purilied from sorghum, pinto bean, quebracho and wattle for six dissimilar protins have been determined by a competitive binding assay. The results indicate that tannin/protein interactions may be specific for different tanains as well as for different proteins. The highly specific interactions suggest that the differences in affinity are functionally...
متن کاملAnalysis and decomposition of condensed tannins in tree leaves
In the past decades, many studies have shown that tannins (polyphenolic compounds) are involved in defence mechanisms of plants against attack by bacteria, fungi, and herbivores. Little is known about the mechanisms of action of the polyphenolic compounds (Zucker 1983, Scalbert 1991) even though modern analytical methods have improved the analysis of these complex structures (Mole and Watermann...

متن کاملSynthesis of Silver Nanoparticles Using Condensed and Hydrolysable Tannins
The aim of this work was the synthesis of silver nanoparticles using two types of tannins, hydrolysable and condensed, and comparing the properties of incurred colloids. Both tannins are powerful antioxidants (reductants) which differ in their chemical structure as well as certain properties, which influences the formation of silver particles as well as the composition and properties of the res...
