Content of soluble and bound condensed tannins of three tropical herbaceous forage legumes
The soluble, total-bound and ®bre-bound condensed tannins (CT) in Cassia rotundifolia (cassia), Lablab purpureus (lablab) and Macroptilium atropurpureum (siratro) grown in tropical and subtropical regions were determined by the butanol±HCl method. Cassia had the highest total CT content of 29.5 g/kg DM than that of lablab, 16.9 g/kg DM which was intermediate while that of siratro, 12.4 g/kg DM,...
متن کاملBeneficial Effects of Temperate Forage Legumes that Contain Condensed Tannins
The two temperate forage legumes containing condensed tannins (CT) that promote ruminant production are birdsfoot trefoil (Lotus corniculatus L.; BFT) and sainfoin (Onobrychis viciifolia Scop.; SF). Both are well-adapted to the cool-temperate climate and alkaline soils of the Mountain West USA. Condensed tannins comprise a diverse family of bioactive chemicals with multiple beneficial functions...

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 کاملNutritional toxicology of tannins and related polyphenols in forage legumes.
Proanthocyanidins (PA) (condensed tannins) and hydrolyzable tannins (HT) are the two major classes of tannins. Proanthocyanidins are flavonoid polymers. Hydrolyzable tannins are polymers of gallic or ellagic acid esterified to a core molecule, commonly glucose or a polyphenol such as catechin. Proanthocyanidins are the most common type of tannin found in forage legumes. Problems in the analysis...
