Methods in Polyphenol Analysis by Celestino Santos-Buelga,Gary Williamson Pdf

Polyphenols make a vital contribution to the colour, tanning, taste and astringency of so many of society's favourites - from the unique taste of the British cup of tea to a glass of red wine. Found widely in many foods of plant origin, polyphenols are also becoming increasingly recognised as antioxidants in the body, with action on long-term health and reduction in the risk of chronic disease. Due to the importance of polyphenols, it is vital to conduct accurate and sensitive analysis. Providing detailed state-of-the-art research, presented in a practical and effective way, Methods in Polyphenol Analysis looks at the latest techniques in this developing field and includes, among others: New modern techniques, such as LC-MS, LC-NMR and LC-coulometric detection; Chemical and enzymatic synthesis of polyphenol conjugates; and Characterization of oligomeric and polymeric tannins and complex polyphenols. This timely publication is written by highly experienced practitioners in this field and will be invaluable to all academics and industrialists involved in phytochemistry, biochemistry and food science.

Methods in Polyphenol Chemistry by J. B. Pridham Pdf

Methods in Polyphenol Chemistry documents the proceedings of the Plant Phenolics Group Symposium held at the University of Oxford, on 2-4 April 1963. The symposium focused on the methods and techniques which made advances in the chemistry and biochemistry of phenolic compounds possible. The development of paper chromatographic and ultraviolet spectroscopic techniques was particularly important and largely responsible for the rapid growth in knowledge of polyphenols which has occurred during the last 10-15 years. In addition to these two methods other spectroscopic techniques were dealt with at the symposium. Particular mention should perhaps be made of nuclear magnetic resonance spectroscopy which is becoming increasingly important in polyphenol chemistry. Modern chromatographic methods such as thin layer and gas-liquid techniques will probably be used extensively in the future. These will enable the analyses of polyphenol mixtures to be carried out more rapidly and with greater resolution. Polyamide chromatography also has high powers of resolution, although this technique has not been widely used owing to difficulties in obtaining supplies of polyamide powder. This situation has now improved, however.

Phenolic Compounds in Food by Leo M.L. Nollet,Janet Alejandra Gutierrez-Uribe Pdf

Phenolic compounds, one of the most widely distributed groups of secondary metabolites in plants, have received a lot of attention in the last few years since the consumption of vegetables and beverages with a high level of such compounds may reduce risks of the development of several diseases. This is partially due to their antioxidant power since other interactions with cell functions have been discovered. What’s more, phenolic compounds are involved in many functions in plants, such as sensorial properties, structure, pollination, resistance to pests and predators, germination, processes of seed, development, and reproduction. Phenolic compounds can be classified in different ways, ranging from simple molecules to highly polymerized compounds. Phenolic Compounds in Food: Characterization and Analysis deals with all aspects of phenolic compounds in food. In five sections, the 21 chapters of this book address the classification and occurrence of phenolic compounds in nature and foodstuffs; discuss all major aspects of analysis of phenolic compounds in foods, such as extraction, clean-up, separation, and detection; detail specific analysis methods of a number of classes of phenolic compounds, from simple molecules to complex compounds; describe the antioxidant power of phenolic compounds; and discuss specific analysis methods in different foodstuffs.

Antioxidant Activity of Polyphenolic Plant Extracts by Dimitrios Stagos Pdf

“Antioxidant Activity of Polyphenolic Plant Extracts” is a collection of scientific articles regarding polyphenols, that is, substances occurring naturally in plants and exhibiting many beneficial effects on human health. Among polyphenols’ interesting biological properties, their antioxidant activity is considered the most important. This book brings together experts from different research fields on topics related to polyphenols, such as their isolation and purification, assessment of their antioxidant activity, prevention from oxidative stress-induced diseases and use as food additives. The polyphenols used in the present studies are derived from a great variety of plants, ranging from well-known species to rare ones that are only found in specific regions. Moreover, some of the studies provide evidence that polyphenols may be used for the prevention and treatment of common diseases such as diabetes mellitus, Alzheimers’ disease, cardiovascular and intestinal diseases. Importantly, in several of the studies “green extraction methods” for the isolation of polyphenols were developed using modern technologies, where few or no organic solvents were used, in order to minimize environmental and health impacts.
