Hydrolysable tannin oligomers from Rosa davurica

Phytochemistry, 1991
Abstract Three new hydrolysable tannin oligomers, davuriciins D 1 , D 2 and T 1 , along with a main tannin, agrimoniin, have been isolated from the root extract of Rosa davurica . Their structures in which monomeric constituents are linked through a valoneoyl group and/or dehydrodigalloyl group, have been elucidated based on spectral and chemical ...

Coriariin M, a trimeric hydrolysable tannin with dehydrodigalloyl and valoneoyl groups as linking units, and accompanying dimeric hydrolysable tannins from Coriaria japonica

Phytochemistry, 2018
Three oligomeric hydrolysable tannins, coriariins K, L, and M, which were previously undescribed, together with five known hydrolysable tannins were isolated from dried leaves of Coriaria japonica. Their structures were determined based on 1D and 2D NMR spectroscopy, HR-ESI-MS, and ECD spectroscopy experiments. Among the isolated compounds, coriariin M

Flow injection system for hydrolysable tannin determination

Microchemical Journal, 2006
Abstract A flow injection system was proposed to evaluate the transient product of a colorimetric reaction between hydrolysable tannin and potassium iodate (KIO 3 ) solution. The system optimization was accomplished by using statistical methods based on experimental design.

Antimicrobial and Antiviral Activity of Hydrolysable Tannins

Mini-Reviews in Medicinal Chemistry, 2008
Hydrolysable tannins (HTs), secondary metabolites widely distributed in the plant kingdom, are generally multiple esters of gallic acid with glucose. HTs have been shown to be effective antagonists against viruses, bacteria and eukaryotic microorganisms.

Oligomeric hydrolysable tannins from Tibouchina multiflora

Phytochemistry, 1999
Two hydrolysable tannins, nobotanin O and nobotanin P, were isolated from the leaf extract of Tibouchina multiflora (Melastomataceae) and their dimeric and tetrameric structures elucidated on the basis of spectral data and chemical correlations with nobotanin B and K, respectively. Thirteen known hydrolysable tannins including nobotanins A, B, C and J,

Monomeric and dimeric hydrolysable tannins of Tamarix nilotica

Phytochemistry, 2009
An ellagitannin monomer, nilotinin M1 (1), and three dimers, nilotinins D1 (2), D2 (3), and D3 (4), were isolated from leaves of Tamarix nilotica (Ehrenb.) Bunge. Structures were elucidated based on analysis of spectroscopic data and chemical correlations with known compounds.

A dimeric hydrolysable tannin from Camellia oleifera

Phytochemistry, 1994
Camellioferin A, a new dimeric ellagitannin, was isolated, together with 13 known tannins, including camellins A and B, from Camellia oleifera. The structure of the new tannin elucidated by spectroscopic methods.
