Grassby, Terri. "Phenolics and phenolic-polysaccharide linkages in Chinese water chestnut (Eleocharis dulcis) cell walls." Thesis, University of East Anglia, 2008. https://ueaeprints.uea.ac.uk/33057/.

Abstract:

The main aim was to investigate the cell-wall cross-links in Chinese water chestnut (CWC), in particular ferulic-acid-containing phenolic-polysaccharide cross-links. The secondary ~ims were: to understand the gross composition of C''!C cell walls froin the parenchyma, epidermis and sub-epidermis tissues of the corm and the -role of cell-wall composition in the plant's physiology, and to determine whether CWC contained higher oligomers of ferulic acid. Cell-wall composition was investigated using a range of chemical analyses including alkali phenolic extraction and methylation analysis. Chemica

Abstract:

Epidemiological studies have suggested associations between the consumption of plant foods and beverages, especially those rich in phenolic compounds, and the prevention of chronic diseases, and there is a growing evidence indicating that these dietary phytochemicals are involved in enhancing long-term health. The antioxidant capacity of these compounds appears to be, at least in part, responsible the reduction of certain oxidative stress pathologies. Common fruits, vegetables and nuts available in supermarkets in Scotland were screened to identify products that are rich in phenolic antioxidan

Abstract:

Olive leaf extract (OLE) contains polyphenols unique to the olive plant (Olea europaea), namely the secoiridoid oleuropein and its derivative hydroxytyrosol (HT). As such, OLE contains a similar phenolic profile to olive oil. Early evidence suggests some beneficial effects of OLE on human health. We conducted a double-blind, controlled, cross over, postprandial study, in which healthy individuals (n=18) consumed OLE capsules containing 58 mg oleuropein and 4 mg HT or a control.

Abstract:

Grape pomace is a by-product of wineries. It is one of the most potent antioxidant sources due to its high phenolic content. In this thesis study, ultrasound assisted extraction of phenolic compounds from Merlot grape pomace has been studied. The effects of sonication time, subsequent extraction time in shaking water bath at 45&deg<br>C and composition of the solvent on extraction efficiency and recovery of phenolics were studied by response surface methodology. Folin-Ciocalteu colorimetric method was used to analyze effects of process parameters on the total phenolic content of the extracts.

High performance liquid chromatography (HPLC) is the preferred method for phenolic analysis; however, conventional HPLC methods offer limited separation power and often provide incomplete separation of the large number of components present in natural phenolic extracts.

Wood is a naturally occurring, complex, structured, polymeric material comprised of a structural matrix in which are embedded a vast variety of extractible compounds. The organic carbon-rich matrix is susceptible to biodeterioration by a wide range of bacterial, fungal, insect and other organisms, despite protective effects of the extractives. Wood preservatives developed over the past 50 years have provided efficient ways of preventing biodeterioration, but many of them are under threat from an increasingly chemophobic populace.

The Caco-2 cell culture model of small intestinal enterocytes was optimised to mimic the chronic supplementation with physiological concentrations of fatty acid. Treatment with polyunsaturated fatty acids (PUFA) changed the fluidity of the brush border membrane, but this modification did not affect transepithelial transport of the test compounds caffeic acid, ferulic acid and epicatechin.

Background: Clinical and epidemiologic studies have investigated the effects of diet, physical activity, and inflammation on the risk of colorectal adenoma occurrence and recurrence. Inflammation has been proposed as a mechanism of action for the development of colorectal adenoma and cancer. Research indicates that fruit phenolic exposure may attenuate the inflammatory response and some data suggest that berries are effective in mitigating this process. Inflammatory cytokines such as interleukin-6 (IL-6), C-reactive protein (CRP), and tumor necrosis factor alpha (TNF-α) are of particular in

Doctor of Philosophy<br>Department of Human Nutrition<br>Weiqun Wang<br>Many functional food related bioactive compounds have been discovered and draw the attention of scientists. This dissertation focused on sorghum phenolic compounds and omega-3 polyunsaturated fatty acids. Study 1: phenolic agents in plant foods have been associated with chronic disease prevention, especially cancer. However, a direct evidence and the underlying mechanisms are mostly unknown. This study selected 13 sorghum accessions and was aim to investigate: (1) the effect of extracted sorghum phenolics on inhibiting ca

Abstract:

The phenolic compounds as food components represent the largest group of secondary metabolites in plant foods. The phenolic compounds, e.g. chlorogenic acid (CQA), are susceptible to oxidation by enzymes specially, polyphenol oxidase (PPO) and at alkaline conditions. Both enzymatic and non-enzymatic oxidations occur in the presence of oxygen and produce quinone, which normally further react with other quinone to produce colored compounds (dimers), as well as is capable of undergoing a nucleophilic addition to proteins. The interactions of proteins with the phenolic compounds have received cons

Abstract:

A healthy and proper diet is essential to prevent the onset of various diseases, as with the diet we can also introduce harmful substances. Among others, the oxysterols are particularly relevant; they can be absorbed from the diet and are the oxidized products of cholesterol present in cholesterol-containing foodstuffs after cooking, processing and storage, such as meat, fish, dairy products and eggs. They can be also generated endogenously from either the spontaneous or enzymatic oxidation of cholesterol. Oxysterols have been shown to exert several in vitro and in vivo biochemical activitie
