Condensed vegetable tannins: Biodiversity in structure and biological activities
Biochemical Systematics and Ecology, 1999Abstract Proanthocyanidins, as an important class of secondary plant metabolites, are in many cases the active principles of the medicinal plants from which they are isolated. The structural complexity and conformational properties of the lower molecular weight oligomers have been investigated thoroughly, while the chemistry of the polymers still ...

Recovery of vegetable tannins from divi‐divi pods
Journal of Chemical Technology & Biotechnology, 1995AbstractAn experimental survey was developed to determine optimal operational conditions when extracting tanning materials from mied divi‐divipods with a 10% (v/v) alcohol–water solution. The study included runs at both laboratory and pilot levels.

Influence of vegetable tannins on nitrification in soil
Plant and Soil, 1964A laboratory study was performed on the effects of pure preparations of vegetable tannins on the nitrification of ammonium sulphate in soil. Purified preparations of wattle and of chestnut-oak tannins used at concentrations of 0.50, 1.00, and 2.00% (w/w) showed a fairly strong inhibition on the formation of nitrate only during the first two weeks ...
