Download or read book Alkaloids Chemical and Biological Perspectives written by S. William Pelletier and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 8 of this series presents four timely reviews on alkaloids: Chapter 1 is a magnificent and monumental review of curare, "a group of dart and/or arrow poisons varying in composition and featuring muscle relaxation as their basic pharmacological action." The fascinating history of curare is recounted, beginning with early encounters by the Spanish Conquistadores through its use as arrow poisons by the forest tribes in hunting and warfare, its chemistry, ethnography, botany and pharmacology. A terminal section of this chapter treats the development of modern muscle relaxants. This chapter thus traces how curare-initially only a crude plant extract-has given rise to the widely used and very important neuromuscular blocking agents of today. The precise role of plant secondary metabolites and their interactions with insect herbivores have been focal points for research by chemists, botanists and entomologists for many years. Alkaloids and their glycosides are frequently involved as feeding deterrents. Chapter 2 treats the relationships between the chemistry of alkaloids in host plants and the effects that these compounds may have on insect herbivores. Interestingly, an alkaloid produced by a plant may manifest different effects on different insects.
Download or read book Foodborne Disease Handbook Second Edition written by Y. H. Hui and published by CRC Press. This book was released on 2019-08-08 with total page 855 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Foodborne Disease handbook, Second Edition, Revised and Expanded, could not be appearing at a more auspicious time. Never before has the campaign for food safety been pursued so intensely on so many fronts in virtually every country around the world. This new edition reflects at least one of the many aspects of that intense and multifaceted campaign: namely, that research on food safety has been very productive in the years since the first edition appeared. The Handbook is now presented in four volumes instead of the three of the 1994 edition. Volume 3 of this series of books on food gums and hydrocolloids continues with a pragmatic coverage of three important categories of gum, i.e., the cellulose gums, the plant seed gums, and the pectins. The chemical, physical and functional properties of each of the important food gums in these categories are reviewed and discussed in relation with their utility in food product applications. The four volumes are composed of 86 chapters, a 22% increase over the 67 chapters of the first edition. Much of the information in the first edition has been carried forward to this new edition because that information is still as reliable and pertinent as it was in 1994. This integration of the older data with the latest research findings gives the reader a secure scientific foundation on which to base important decisions affecting the public‘s health.
Download or read book Alkaloids written by Hans-Ferdinand Linskens and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is refreshing to find a book treating alkaloid analysis with all the latest techniques such as inverse-detected two dimensional NMR, GC/MS, and HPLC associated techniques. There have been many developments in the field of alkaloid analysis since the 1950s, not the least of which are the various powerful spectroscopic methods, which dominate this volume. Included also are the various aspects of tobacco alkaloids and analysis in various situations. The complexities of sampling and analysis in tobacco smoke is explained. Analysis of alkaloids produced by tobacco root cell cultures is included, while genetic and chemical analysis is described for Papaver, a plant of considerable medicinal significance.
Download or read book Plant Secondary Metabolism written by David S. Seigler and published by Springer Science & Business Media. This book was released on 1998-12-31 with total page 774 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Secondary Metabolism presents a basic understanding of the origin of the compounds, the nature of the precursors involved, and the basic reactions, mechanisms, and stereochemistry. The origin of groups of secondary metabolites is linked to evolutionary principles, and their biological activity is viewed in a context of chemical ecology. Topics are treated comprehensively, enabling the reader to understand not only a particular group of compounds, but also how each group fits into the whole. In addition, the text allows readers to systematically survey various secondary metabolites and gain a quick working knowledge, which can be applied to problems in a particular field. Those researchers and students who will be most intrigued by this publication's broad overview on plant secondary metabolites come from a diverse range of disciplines, including agronomy, anthropology, biochemistry, biology, botany, chemistry, ecology, entomology, food science, forestry, geology, horticulture, pharmacognosy, plant biology, plant sciences, toxicology, and zoology.

Available in PDF, EPUB and Kindle. Book excerpt: During the last few decades, research into natural products has advanced tremendously thanks to contributions from the fields of chemistry, life sciences, food science and material sciences. Comparisons of natural products from microorganisms, lower eukaryotes, animals, higher plants and marine organisms are now well documented. This book provides an easy-to-read overview of natural products. It includes twelve chapters covering most of the aspects of natural products chemistry. Eac chapter covers general introduction, nomenclature, occurrence, isolation, detection, structure elucidation both by degradation and spectroscopic techniques, biosynthesis, synthesis, biological activity and commercial applications, if any, of the compounds mentioned in each topic. Therefore it will be useful for students, other researchers and industry. The introduction to each chapter is brief and attempts only to supply general knowledge in the particular field. Furthermore, at the end of each chapter there is a list of recommended books for additional study and a list of relevant questions for practice.

Download or read book Optimization of Chromatographic Selectivity written by P.J. Schoenmakers and published by Elsevier. This book was released on 1986-08-01 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first detailed description of method development in chromatography - the overall process of which may be summarized as: method selection, phase selection, selectivity optimization, and system optimization. All four aspects receive attention in this book.Chapter 1 gives a short introduction, describes chromatographic theory and nomenclature, and outlines the method development process. Chapter 2 describes guidelines for method selection, and quantitative concepts for characterizing and classifying chromatographic phases. Selective separation methods, from both gas and liquid chromatography are given in Chapter 3; the main parameters of each method are identified and simple, quantitative relations are sought to describe their effects. Criteria by which to judge the quality of separation are discussed in Chapter 4 with clear recommendations for different situations. The specific problems involved in the optimization of chromatographic selectivity are explained in Chapter 5. Optimization procedures, illustrated by examples, are extensively described and compared on the basis of a number of criteria. Suggestions are made both for the application of different procedures and for further research. The optimization of programmed analysis receives special attention in Chapter 6, and the last chapter summarizes the optimization of the chromatographic system, including the optimization of the efficiency, sensitivity and instrumentation.Those involved in developing chromatographic methods or wishing to improve existing methods will value the detailed, structured way in which the subject is presented. Because optimization procedures and criteria are described as elements of a complete optimization package, the book will help the reader to understand, evaluate and select current and future commercial systems.
