Mode 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...

8-33 (FeNH 4 (SO 4 ) 2 .12H 2 O) dissolved in 0.15 mL of 0.1 M HCl to 400 μg of CT dissolved in 1 mL of 68% aqueous methanol. (ii) Ascorbic acid concentrations in the final sample/reagent matrix of 0-400 μg mL -1 prepared in 1 mL of 68% aqueous methanol, containing 400 μg of CT. (iii) Sodium metabisulphite (Na 2 S 2 O 5 ) concentrations of 0-263 μg mL in the final sample/reagent matrix, prepare...
متن کاملStability of peptide-condensed plasmid DNA formulations.
Low molecular weight homogeneous peptides were used to form peptide/DNA condensates. A peptide possessing 18 lysines was found to protect plasmid DNA from serum endonuclease and sonicative-induced degradation whereas a shorter peptide possessing 8 lysines dissociated in 0.1 M sodium chloride and failed to protect DNA from enzymatic degradation. Peptide-condensed DNA showed no change in the rati...
متن کاملVanillin-condensed tannin study using flow injection spectrophotometry.
Studies involving the kinetic reaction between vanillin and condensed tannins were developed using a flow injection system with spectrophotometric determination. A solution of the monomeric compound (-)-epicatechin was used as the analytical standard. This compound was chosen due to its structure, which is similar to a polymeric unit of the condensed tannin present in plants. The results indica...
