Methods in Polyphenol Chemistry


Book Description

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.













Recent Developments in the Chemistry of Natural Phenolic Compounds


Book Description

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.
