Bound phenolic acids in terrestrial humic acids
Science of The Total Environment, 1992Abstract Bound phenolic acids, released from soil humic acids (HA) by hydrolysis, were determined in a number of situations involving contrasting vegetation. In a study of three vegetation zones on the flanks of a volcano in central Mexico, changes in vegetation were associated with changes in relative proportions of lignin-derived phenolic acids.

Determination of free and bound phenolic acids in beer
Food Chemistry, 2004The aim of this study was the qualitative and quantitative determination of free and bound phenolic compounds, mainly phenolic acids, in beer. In spite of the wide literature describing the content of free phenolic acids in beer, data concerning its content of bound forms are scarce or missing. Moreover, the experimental conditions commonly reported in

The Wall-Bound Phenolics of Chinese Water Chestnut (Eleocharisdulcis)
Journal of the Science of Food and Agriculture, 1996Chinese water chestnut (CWC) is a vegetable in which the edible storage parenchyma exhibits thermal stability to texture. This property has been attributed to the presence of large quantities of simple phenolics which exhibit pH-dependent autofluorescence.

Reaction of substituted phenols with thermostable laccase bound to Bacillus subtilis spores
Biotechnology Letters, 2003A strain of B. subtilis produced 1.8 times more laccase on sporulation medium than on non-sporulation medium. Spores oxidized mono- and di-methoxyphenols (0.1 mM) at 50 degrees C. The half-life of laccase bound to spores was about 2 d and the substrate was repeatedly removed by spores recovered from the reaction mixture.

Oxidative phenol coupling catalyzed by polymer‐bound copper‐imidazole complexes
Makromolekulare Chemie. Macromolecular Symposia, 1992AbstractPolymer‐bound imidazole‐copper(II) complexes were investigated and applied as catalysts for oxidative coupling (polymerization) of 2,6‐dialkylphenols. These polymeric catalysts were also immobilized on silica particles through adsorption, quaternization and grafting. Especially, the grafted catalysts showed interesting catalytic properties, e.g.

Modification of the Lowry assay to measure proteins and phenols in covalently bound complexes
Analytical Biochemistry, 2005It is well established that phenols interfere with many routine protein assays and a number of protocols have been developed to overcome this. One such method is based on the differences in response obtained with the Lowry assay in the presence and absence of copper.

Methods for Determining Cell Wall-Bound Phenolics in Maize Stem Tissues
Journal of Agricultural and Food Chemistry, 2018We compared two methods with different sample pretreatment, hydrolysis, and separation procedures to extract cell wall-bound phenolics. The samples were pith and rind tissues from six maize inbred lines reportedly containing different levels of cell wall-bound phenolics.

Rubber bound phenolic antioxidant and its application in thermoplastic elastomer
Advances in materials Research, 2014Natural rubber bound phenolic antioxidant, 2,6-di-tert-butyl-4-vinylphenol (2,6-DBVP), was prepared from natural rubber and 2,6-DBVP in both solution and melt state. The 2,6-DBVP had been synthesized from 3,5-di-tert-butyl-4-hydroxybenzaldehyde and methyltriphenylphosphonium iodide (MePPh3I) by Wittig reaction (0°C for 2 hrs, N2 atmosphere).
