Biological Activity of Phenolics in Chicks and Rats
… enzyme levels compared with chicks fed no phenolics. Chicks fed 0.5% para-coumaric acid had lower rates of gain than did chicks fed control or other phenolic-containing diets. Rats fed these phenolics had similar cytochrome P-450 levels. Vanillin had no antioxidant activity when compared to …

Oil palm phenolics suppresses oxidative stress and inflammation
Water-soluble Oil Palm Phenolics (OPP), derived from Elaeis guineensis, contains a unique blend of plant phenolics. Recent cell and animal studies have demonstrated positive health benefits in a number of different organ systems, with almost no noticeable side effects. Its efficacy and non-toxicity …

Using Esterase and Laccase Enzymes to Derivatize Bioactive Plant Phenolics for Altered Chemistry
Plant phenolics have notable antioxidant activity and there is potential to improve their action by chemical modification. Two enzyme classes carry out reactions that can act on the hydroxyl moiety of phenolics. Esterase enzymes can be used in non-aqueous solvents to esterify a long chain acyl …

Potential influence of blueberry and black raspberry pomace phenolics on inflammatory cytokines in coronary cells
… of blueberry and black raspberry pomace phenolics, and evaluate the potential efficacy of these products compared to anthocyanin-rich extracts as anti-inflammatory compounds in fatty acid-induced inflammation. A previous study identified myristic and palmitic acids as the most …

Tropical citrus antioxidants and catabolism of phenolics in green tea, coffee, cocoa and orange juice
Citrus fruits are of special interest as they accumulate large amounts of flavonoids and are consumed in substantial quantities worldwide. Despite extensive research on citrus flavonoids, many compounds remain unidentified in tropical citrus species. High performance liquid chromatography with mass …

Characterisation of phenolic antioxidants in fruits and vegetables : bioavailability of raspberry phenolics in humans and rats
… Reducing Antioxidant Potential (FRAP). Total Phenolics content (TPC) was also quantified using the Folin-Ciocalteau assay. Due to interest in the Zutphen study in the early 1990's that showed that dietary intake of flavonols was inversely correlated with the incidence of coronary heart …

Analysis of phenolics and other phytochemicals in selected Malaysian traditional vegetables and their activities in vitro
… hypothesis that other components in addition to phenolics also contributed to the total antioxidant activities in the plants, the next objective, which was presented in Chapter 4, was to investigate the occurrence of phytochemicals such as triterpenes, carotenoids, α-tocopherol and vitamin C. The …

Interactions of food proteins with plant phenolics – modulation of structural, techno- and bio-functional properties of proteins
… bean has a higher diversity and content of phenolics, where besides the CQA isomers and their esters, other conjugates like feruloylquinic acids were also identified, thus documenting differences in phenolic profiles for the two coffee types (Coffea arabica and Coffea robusta). Coffee …

Harmful effect of oxysterols in the gut and at systemic level: modulatory activity of olive oil phenolics
… of compounds with antioxidant action, such as phenolics, is able to counteract the oxidative stress and inflammatory response in the intestine and inhibit the onset of the main related diseases. Extra virgin olive oil polyphenols in particular, recognized for their strong antioxidant property …

Intestinal absorption and bioavailability of coffee phenolics and green tea polyphenols: a study in healthy and ileostomy volunteers
Flavonoids and phenolic compounds (aka polyphenols) are phytochemicals, thought to participate in plant development and defence mechanisms. Polyphenols are ubiquitous plant secondary metabolites, and are usually found conjugated as glycosides or esters. These compounds have been of particular …

EVALUATION OF YAK-KONG SOYBEAN (GLYCINE MAX) FOR ITS PHENOLICS AND METABOLITES WITH A FOCUS ON ATHEROSCLEROSIS PREVENTION
… and historical background and was evaluated its phenolics and their metabolites with a focus on prevention of CVDs. First, antioxidant activities and phenolics of YK were analyzed. In comparison to common yellow and black soybean cultivars, YK contained significantly higher concentrations of …

Influence of processing design on the accessibility of phenolics in blueberry (vaccinium corymbosum L.) pureés: the effect of hydration and microstructural properties
I frutti di mirtillo (Vaccinium corymbosum L.) costituiscono una importante fonte naturale di composti fenolici e puree congelate preparate da queste bacche possono essere considerate prodotti versatili a elevato valore aggiunto, ottenuti senza che ci siano perdite dovute a scarti di lavorazione e, …

Processing induced changes in phenolic concentration and antioxidant capacity of corn for production of corn flakes
… 1980s. This study was designed to examine how phenolics and antioxidant capacity change during processing of corn into flakes, and to evaluate the effects of processing condition, corn genotype, and growing year on phenolics, with the ultimate goal of improving the nutritional quality of corn …

Interaction Between Insects and Apple (Malus X Domestica Borkh.): Insect Behavior, Genotypic Preference, and Plant Phenolics With Emphasis on Japanese Beetle (Popillia Japonica Newman)
Leaves and fruit of nine apple (Malus x domestica Borkh.) genotypes were evaluated for insect injury in 1998 and 1999. Foliar and fruit injury from 12 insect species was inconsistently affected by genotype. Spraying trees with oil affected neither fruit insect injury nor fruit phytotoxicity. In …

Interactions of Phenolic Monomers With Digestion and Metabolism
… cell walls were examined. Most alkali-labile phenolics were present in both the cell soluble and cell wall fractions, whereas nitrobenzene oxidation products were restricted to cell wall material. Roughages differed in content of phenolic monomers, with grasses generally having higher …

Carbon based secondary metabolites in African savanna woody species in relation to anti-herbivore defense
… compromises its simple quantification and total phenolics, which is a measure of general foliar phenolics, includes many different low molecular weight phenolics. Some of these low molecular weight phenolics have been shown to deter herbivory individually or in combination with others. The growth …

Influence of dietary polyphenols on carbohydrate intestinal digestion and absorption
… typically derived from experiments with pure phenolics and phenolic rich extracts have pointed to this benefit being associated with two potential mechanisms: (1) the ability of specific polyphenolics to inhibit carbohydrate digestion (amylase and glucosidase) and (2) polyphenolic inhibition …
