About 1958, the late Professor R. E. ALSTON and Professor B. L. TURNER, both of the Department ofBotany, The University ofTexas at Austin, initiated a general systematic investigation ofthe legurne genus Baptisia. They found that flavonoid patterns, as revealed by two-dimensional paper chromatography, were valid criteria for the recognition of the Baptisia species and for the documentation of their numerous natural hybrids. Later, they showed that the flavonoid chemistry could be used for the analysis of gene flow among populations. At that time no attempt was made to even partially identify the flavonoids which were detected chromatographically. Neverthe1ess, it soon became apparent that the full value of the chemical data for systematic purposes required knowledge of the structures of the flavonoids. In 1962, one of us (T.J.M.) in collaboration with Drs. ALSTON and TURNER beg an the chemical analysis of the more than 60 flavonoids which had been chromatographi cally detected in the 16 Baptisia species. In the intervening years, a number of chemists and botanists, inc1uding Drs. K. BAETCKE, B. BREHM, M. CRANMER, D. HORNE, J. KAGAN, B. KROSCHEWSKY, J. MCCLURE, H. RÖSLER, and J. WALLACE, participated in the devel opment of techniques and procedures for the rapid identification of known flavonoids and in the structure determination of new flavonoids. In addition, the flavonoid chem istry of many plants other than Baptisia was investigated.

Offering a wide ranging view of this important class of plant pigments, after a brief examination of the history & literature of flavonoids, this book explores structural variation of all subclasses of flavonoids, techniques for isolation, purification, & determination of structures, chemical syntheses, biosynthesis & genetics, patterns of distribution in the plant kingdom, & uses. Lastly, the functions of flavonoids in nature are investigated, as well as ways in which these compounds may have a more direct impact upon the human race. Contents: Introduction & Historical Perspective * Structural Variation * Occurrence & Distribution of Flavonoids * Extraction, Purification, & Identification of Flavonoids * Synthesis & Interconversions of Flavonoids * Biosynthesis & Genetics * Flavonoid Functions in Nature * Human Uses of Flavonoids

Flavonoids are abundant secondary metabolites found in plants and fungi that have various roles in these organisms, including pigmentation, cell signalling, plant defence and inter-organism communication. Due to their abundance in nature, flavonoids are also important components of the human diet, and the last four decades have seen an intense study focused on the structure characterization of flavonoids and on their roles in mammal metabolism. This book reviews most of the well-established activities of flavonoids, and we also present more recent research studies on the area of flavonoids, including the chemical aspects of structure characterization of flavonoids, the biosynthesis of flavonoids in model plants as well as their role in abiotic stress situations and in agriculture, the role of flavonoids in metabolism and health and their importance in foods, from consumption to their use as bioactive components.

The flavonoids, one of the most numerous and widespread groups of natural constituents, are important to man not only because they contribute to plant colour but also because many members (e.g. coumestrol, phloridzin, rotenone) are physiologically active. Nearly two thousand substances have been described and as a group they are universally distributed among vascular plants. Although the anthocyanins have an undisputed function as plant pigments, the raison d'etre for the more widely distributed colourless flavones and flavonols still remains a mystery. It is perhaps the challenge of discovering these yet undisc10sed functions which has caused the considerable resurgence of interest in flavonoids during the last decade. This book attempts to summarize progress that has been made in the study of these constituents since the first comprehensive monograph on the chemistry of the flavonoid compounds was published, under the editorship of T. A. Geissman, in 1962. The present volume is divided into three parts. The first section (Chapters 1-4) deals with advances in chemistry, the main emphasis being on spectral techniques to take into account the re cent successful applications of NMR and mass spectral measurements to structural identifications. Recent developments in isolation techniques and in synthesis are also covered in this section. Advances in chemical knowledge of individual c1asses of flavonoid are mentioned inter aha in later chapters of the book.

This reference work provides a wealth of information regarding medicinal plants and phytochemicals. It is addressed both to researchers and teachers. The handbook describes phytochemicals, which, by the strictest definition, are chemicals that are produced by plants. During the last decades, more and more groups became actively involved in exploring plants for useful metabolites that lead to the identification of several useful curative agents and many promising molecules to fight and/or prevent diseases, including carcinogenesis and stroke. But when we talk about phytochemicals, there are also medicinal plants where not a single molecule is responsible for the observed properties. This reference work therefore reviews and compiles the information on both these aspects. The volumes contain contributions on phytochemicals and herbal extracts. A large number of natural products obtained from plants and microorganisms is used in cosmetic, drug, flavor and fragrance industries. For this compilation, a range of the most important medicinal herbs and phytochemicals were selected and are described by the recognized authors in the field. The present reference work encompasses the information about well established phytochemicals, biology and biotechnology of medicinal plants or their products, their biosynthesis, novel production strategies, demand and uses, metabolism and bioavailability. There is a surge of information published in recent years on herbal medicine and their pharmacologic effects with single books available on varied subjects. However, all this information is widespread and difficult to overview. Researchers who wish to keep a pace with the rapidly developing field of natural products can now consult this newly compiled handbook to find all information about bioactive molecules and medicinal plants thoroughly compiled in one place!

Based on the results of the latest congress of the European Association for the Study of the Liver (EASL), this volume makes excellent reading since it explores in detail the role of free radical reactions in liver diseases. Studies in recent years using various methods have shown that free radicals play an important role in toxic liver disorders. For this reason, the current scientific knowledge is presented in this balanced, clinical portrayal. The account refers to the many observations, experiencesand evaluations that have been made both clinically and experimentally. Two major areas discussed concern the pathophysiological changes by free radicals and the therapeutic possibilities that have come to light.
