Hydrolysable tannins and related compounds from Castanea mollissima

Phytochemistry, 1988
Abstract A chemical examination of the leaves of Castanea mollissima has led to the characterization of four new polyphenolic compounds, castamollissin, isochesnatin, isochestanin and castanin. In addition, the occurrence of 20 known hydrolysable tannins and related compounds was demonstrated.

Hydrolysable tannins as chemotaxonomic markers in the rosaceae

Phytochemistry, 1992
Abstract A HPLC survey of leaves of 80 plants (62 species, 15 hybrids, one variety and two cytotypes) from 18 genera of four subfamilies of Rosaceae, using five oligomeric hydrolysable tannins, five monomeric hydrolysable tannins, and chlorogenic acid as reference compounds, showed that the oligomers can be used as chemotaxonomic markers for the ...

Polyurethanes from hydrolysable tannins obtained without using isocyanates

Industrial Crops and Products, 2014
Abstract Hydrolysable chestnut tannins, which contain several hydroxyl groups, were reacted with dimethyl carbonate, and then with hexamethylenediamine. The dried product was analyzed in MALDI-TOF, 13 C NMR and FTIR spectrometry. The spectra revealed the presence of urethane functions and their yield was relatively high.

Analysis of condensed and hydrolysable tannins from commercial plant extracts

Journal of Pharmaceutical and Biomedical Analysis, 2006
High performance liquid chromatography (HPLC)/DAD and MS qualitative and quantitative analyses of polyphenols, hydrolysable and condensed tannins from Pinus maritima L. and tannic acid (TA) extracts were performed using normal and reverse phase. Normal-phase HPLC was more suitable for pine bark (PBE) and tannic acid extracts analysis.

Tolerance mechanisms of streptococci to hydrolysable and condensed tannins

Animal Feed Science and Technology, 2005
Abstract In vitro growth assays demonstrated that Streptococcus bovis JB1 was sensitive to tannic acid (TA), acacia (AT), and calliandra tannins (CT), while Streptococcus gallolyticus 2.2 was tolerant. At low levels of tannin, S. bovis JB1 exhibited some tolerance but this was always less than for S. gallolyticus 2.2.

Circular dichroism of hydrolysable tannins-I ellagitannins and gallotannins

Tetrahedron Letters, 1982
Abstract The Cotton effects around 235, 265 and 285 nm in the CD spectra of twenty hydrolysable tannins and related compounds were empirically correlated with the stereostructures of ellagitannins and gallotannins.

Scope of Hydrolysable Tannins as Possible Antimicrobial Agent.

Phytotherapy research : PTR, 2017
Hydrolysable tannins (HTs) are secondary metabolites from plants, which are roughly classified into gallotannins and ellagitannins having gallic acid and ellagic acid residues respectively attached to the hydroxyl group of glucose by ester linkage.
