Synthesis and performance of phenolic polybutadiene‐bound stabilizers
Journal of Applied Polymer Science, 2002AbstractAn antioxidant derivative, 6‐sulfanylhexyl 3‐(3,5‐di‐tert‐butyl‐4‐hydroxyphenyl)propanoate, was synthesized and examined. With a radical initiator, the addition of this compound to pending vinyls of OH‐telechelic, low molecular weight liquid polybutadiene (LBH) was performed to various degrees of conversion to form polymeric antioxidants (PAOs)

Effect of Storage on Wall-Bound Phenolics in Green Asparagus
Journal of Agricultural and Food Chemistry, 2002The cell walls of green asparagus spears have been analyzed for their phenolic and carbohydrate composition as modified by postharvest storage. Esterified phenolic components were released by sequential alkaline hydrolysis and identified and quantified by diode array HPLC.

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.

Flavanol and Bound Phenolic Acid Contents in Different Barley Varieties
Journal of Agricultural and Food Chemistry, 2006Different barley varieties, consisting of hulled and hull-less types, of normal, waxy, and high amylose starch, as well as two-rowed and six-rowed types, were analyzed for their main proanthocyanidins and bound phenolic acids. Variations in proanthocyanidin and phenolic acid contents were studied in different barley types as well as inter-relationships

Importance of Insoluble-Bound Phenolics to Antioxidant Properties of Wheat
Journal of Agricultural and Food Chemistry, 2006Two commercial samples of soft (70% Canadian Eastern soft red spring and 30% Canadian Eastern soft white winter) and hard (90% Canadian western hard red spring and 10% Canadian Eastern hard red winter) wheats were used to obtain different milling fractions. Phenolics extracted belonged to free, soluble esters and insoluble-bound fractions.

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.

Distribution of insoluble bound phenolic acids in barley grain
Journal of the Science of Food and Agriculture, 1984AbstractInsoluble bound phenolic acids were analysed by g.l.c. and by h.p.l.c. in eight abraded fractions of barley grain. Vanillic, p‐coumaric, ferulic and diferulic acids were identified in all the fractions. Ferulic and p‐coumaric acids were quantitatively the most important.

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.

Ring Opening of a Resin-Bound Chiral Aziridine with Phenol Nucleophiles
The Journal of Organic Chemistry, 2010An efficient and versatile solid-phase route for the preparation of aryl-alkyl ethers is described. Regioselective ring opening of a resin-bound chiral aziridine with phenolic nucleophiles constitutes the key feature of the present protocol that allows incorporation of fluorescent moieties and subsequent on-resin protecting group interconversion ...

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.
