Phenolic Compounds


Book Description

Phenolic compounds as a large class of metabolites found in plants have attracted attention since long time ago due to their properties and the hope that they will show beneficial health effects when taken as dietary supplements. This book presents the state of the art of some of the natural sources of phenolic compounds, for example, medicinal plants, grapes or blue maize, as well as the modern methods of extraction, quantification, and identification, and there is a special section discussing the treatment, removal, and degradation of phenols, an important issue in those phenols derived from the pharmaceutical or petrochemical industries.




Phenolic Compounds in Food


Book Description

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.




Phenolic Compounds


Book Description

Phenolic compounds comprise a broad class of natural products formed mainly by plants, but also microorganisms and marine organisms that have the capacity to form them. Nowadays the interest in these compounds has increased mainly due to their diverse chemical structure and wide biological activity valuable in the prevention of some chronic or degenerative diseases. The functional foods are a rich source of these phytochemicals, and this is the starting point for this book, which shows the state of the art of the phenolic compounds and their biological activity. This book integrates eleven chapters that show the state of the art of diverse biological activity of the phenolic compounds, present in some crops or fruits.




Phenolic Compounds


Book Description

Phenolic compounds are a large family of metabolites that result from the secondary metabolism of plants. Novel insights about phenolic chemical structure, analytical methods, therapeutic effects, sensory properties, viticultural practices to modify their content and the use of these compounds found in agro-industrial wastes have been gathered in this book. A comprehensive overview on phenolic compounds and neurodegenerative disorders, highlighting their antioxidant, anti-inflammatory properties and their effects on Parkinsons disease have been compiled. In relation to antioxidant properties, the metabolism and bioavailability of several hydroxycinnamic acids present in coffee have been studied in detail, and also the methods to determine antioxidant capacity have been included. Different strategies in order to improve the extraction and determination of phenolic compounds in a complex matrix by analytical techniques are provided, reporting problems and new analytical solutions. The role of these compounds in colour stabilisation and also in bitterness and astringency perception has been reported. Moreover, the interactions that take place among no volatile and volatile compounds present in wine affecting sensory perception have been briefly introduced. Furthermore, the use of cover crops in vineyards and their effects on agronomical and enological behaviour -- particularly, their impact on phenolic compounds -- have been highlighted. Finally, the biological properties of phenolic compounds from industrial wastes have been tackled, since they are a promising alternative to transform agro-industrial wastes into a source of natural and healthy compounds.




Phenolic Compounds


Book Description

Phenolic Compounds: Structure, Uses and Health Benefits opens with a discussion on phenolic substances such as gallic acid, catechin, chlorogenic acid, caffeic acid, p-coumaric acid, ferulic acid, and quercetin. The most common analytical methods (based on spectrophotometric, chromatographic or electrochemical techniques) for determining phenolic compounds applied to a wide range of sample sources are presented. Additionally, the authors study the high concentrations of bioactive substances in fruit berries in order to determine the link between daily fruit intake and human health. A review of the modern literature on extraction, filtration, and adsorption that may be combined with advanced oxidation treatments to minimalise the environmental impact of the remaining wastes is presented, especially focusing on phenolic compounds recovery from olive mill liquidwastes. Lastly, the authors provide an overview on the antiradical and antioxidizing properties of calix[n]arenes and calix[n]resorcinols as part of a larger discussion on the impact of preorganization of antioxidant fragments attached to calix[n]arene and calix[n]resorcinol scaffolds and their intramolecular synergy on antioxidant activity.




Lotus japonicus Handbook


Book Description

Legumes are very important plants playing a central role in biological research. They are a key component of sustainable agricultural systems because of symbiotic nitrogen fixation and other beneficial symbiosis with mycorrhizal fungi. Studies on most of the major leguminous crops are hampered by large genome sizes and other disadvantages which have hindered the isolation and characterisation of genes with important roles in legume biology and agriculture. For this reason Lotus japonicus was chosen as a model species for legume research some ten years ago. Since then, many groups around the world have adopted Lotus as a model and have developed numerous resources and protocols to facilitate basic and applied research on this species. This handbook represents the first effort to compile basic descriptions and methods for research in Lotus, including symbiotic processes, cell and molecular biology protocols, functional genomics, mutants, gene tagging and genetic analysis, transformation and reverse genetic analysis, primary and secondary metabolism, and an exhaustive update of the scientific literature available on this plant.




Plant Physiological Aspects of Phenolic Compounds


Book Description

Phenolic compounds are considered secondary metabolites within the physiology of a plant. They have different functions, such as pollination systems, sun protection, protection against pathogens and diseases, etc.Research on these compounds has increased due to the number of molecules they can include and the different biological activities they demonstrate. It is important to know the methods of extracting molecules, the biosynthesis routes, and their relationship with activities that can benefit from their consumption. Therefore, the book includes chapters that provide information on extraction and optimization techniques, biosynthetic pathways, and the identification and characterization of miRNAs involved in the regulation of their biosynthesis.




Enological Chemistry


Book Description

Enological Chemistry is written for the professional enologist tasked with finding the right balance of compounds to create or improve wine products. Related titles lack the appropriate focus for this audience, according to reviewers, failing either to be as comprehensive on the topic of chemistry, to include chemistry as part of the broader science of wine, or targeting a less scientific audience and including social and historical information not directly pertinent to the understanding of the role of chemistry in successful wine production. The topics in the book have been sequenced identically with the steps of the winemaking process. Thus, the book describes the most salient compounds involved in each vinification process, their properties and their balance; also, theoretical knowledge is matched with its practical application. The primary aim is to enable the reader to identify the specific compounds behind enological properties and processes, their chemical balance and their influence on the analytical and sensory quality of wine, as well as the physical, chemical and microbiological factors that affect their evolution during the winemaking process. - Organized according to the winemaking process, guiding reader clearly to application of knowledge - Describes the most salient compounds involved in each step enabling readers to identify the specific compounds behind properties and processes and effectively work with them - Provides both theoretical knowledge and practical application providing a strong starting point for further research and development
