Effect of Condensed Tannin Extracts on Gastrointestinal Nematodes of Small Ruminants
Experiments were carried out to investigate the effect of condensed tannins on gastrointestinal nematodes. In the first two trials (trial 1 and 2) mature and young parasite naïve sheep under artificial haemonchosis were offered a low protein diet containing varying levels of quebracho extract (QT), a model source of condensed tannins. In trial 1, thirty-five mature rams were assigned to five gr...
متن کاملDetermination of condensed tannin monomers in environmental samples by capillary gas chromatography of acid depolymerization extracts
A method for molecular-level quantification of condensed tannin is described that uses acid depolymerization and carbocation capture by phloroglucinol. Resulting monomers and phloroglucinol adducts are trimethylsilyl derivatized, separated by capillary gas chromatography, detected by flame ionization, and quantified relative to standards. Optimal depolymerization conditions were determined for ...
متن کاملMode of Repellent Activity of Condensed Tannin to Quelea
INTRODUCTION Nonlethal chemical repellents are being vigorously investigated to control wildlife feeding in agriculture and silviculture and thus alleviate damages to food, feed, and fibre. Unfortunately, few effective avian repellents have emerged, partly because workers tend to be anthropomorphic in their basic assumptions about target species and repellent action (Rogers, 1978), and partly d...
متن کاملTransformation of Litchi Pericarp-Derived Condensed Tannin with Aspergillus awamori
Condensed tannin is a ubiquitous polyphenol in plants that possesses substantial antioxidant capacity. In this study, we have investigated the polyphenol extraction recovery and 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity of the extracted polyphenol after litchi pericarp is treated with Aspergillus awamori, Aspergillus sojae or Aspergillus oryzae. We have further explored the activ...
