Recent Development in the Chemistry of Natural Phenolic Compounds covers the proceedings of the Third Plant Phenolics Group Symposium, held in April 1960. This symposium brings together important and interesting developments in the chemistry of naturally occurring phenolic compounds. This book is divided into 12 chapters that specifically concern with the biosynthesis and the determination of the structure of phenolic natural products. The first three chapters discuss the various aspects of biosynthesis and the structural and biogenetic relationships among a large number of natural products. These chapters also consider the biosynthesis of flavonoids, with particular reference to the isoflavones. The succeeding chapter highlights the variety of structures shown by phenolic compounds containing terpenoid substituents. Another chapter deals with the recent syntheses of various natural products by methods involving oxidative coupling of phenolic precursors. Other chapters are devoted to the relationship of phenolic precursors to natural biosynthetical routes. The rest of the book deals with structural investigations, which have led to the recognition of several classes of natural products. This book is of great value to organic chemists and researchers.

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.

This work responds to the need to find, in a sole document, the affect of oxidative stress at different levels, as well as treatment with antioxidants to revert and diminish the damage. Oxidative Stress and Chronic Degenerative Diseases - a Role for Antioxidants is written for health professionals by researchers at diverse educative institutions (Mexico, Brazil, USA, Spain, Australia, and Slovenia). I would like to underscore that of the 19 chapters, 14 are by Mexican researchers, which demonstrates the commitment of Mexican institutions to academic life and to the prevention and treatment of chronic degenerative diseases.

Index to Reviews, Symposia Volumes and Monographs in Organic Chemistry For the Period 1961-1962 aims to help research workers, teachers, and students to locate quickly those current reviews in which they may be interested. The format used in the 1940-1960 Index has been retained. While the 1961-1962 issue stands on its own, it will be most useful in conjunction with the 1940-1960 volume. Complete author and subject indexes are included, with adequate cross-indexing in the latter. While the majority of articles listed is directly on organic chemistry, there are many which border on biochemistry, pharmaceutical chemistry, bacteriology, technological developments, etc. The volume is organized into three parts. Part I contains reviews in journals and periodic publications. Part II presents reviews in symposia, collective volumes, and non-periodical publications. Part III lists monographs on organic chemistry, 1961-1962. Included this volume are a number of articles which deal specifically with hazards in the use of various chemicals, such as perchlorates, peroxides, solvents, insecticides, etc. A selection of articles from the Journal of Chemical Education is provided as well as articles in the International Edition of Angewandte Chemie, published in English.

The chemistry of phenols tends to be ignored in organic chemical textbooks and to be lost amongst the many classes of functional derivatives. This volume is not intended to provide a textbook approach but rather to give an account of developments in phenol chemistry in the last two decades.Features of this book:• Numerous phenolic systems have been covered in detail, e.g. phenolic propanoids.• The emphasis throughout has been on synthesis, on what can be achieved by the use of phenolic intermediates and in the construction of phenolic end products.• Many chapters enable the reader to refer to the original literature wherever possible.• Various chapters provide a fund of tutorial material and problems for undergraduate studies and further, which will encourage perusal of the literature. Some 2000 references to applied and academic papers are given.Phenols are ubiquitous substances and now it is more widely accepted that there are pros and cons connected with their usage. The pros for compounds are well-known and are illustrated by perennial panaceas such as aspirin, paracetamol, codeine, etc. The cons are less obvious because they are also materials deeply entrenched in our standard of living and in most cases inherent hazards have only recently come to light. The book will be of interest to postgraduate students in academic and industrial work.

Enzyme Chemistry of Phenolic Compounds documents the proceedings of the Plant Phenolics Group Symposium held at Liverpool on April 11-12 1962. This book focuses on the interaction of enzymes and phenolic compounds, oxidation-reduction systems in plants and microorganisms, and phenolase complex. Other topics discussed include purification of phenol oxidases; enzyme-substrate specificity in potato polyphenol oxidase; tocopherols; and role of ubiquinone and plastoquinone in plant metabolism. Hydrolytic enzymes; enzyme inhibition by phenolic compounds; tannin inhibition of plant mitochondria; and aromatic acid-reducing systems in fungi are also deliberated in this selection. This publication is beneficial to students and biochemists researching on enzyme and phenolic compounds.

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.
