Nuclear magnetic resonance techniques have advanced dramatically in recent years, and are now more powerful and more versatile than ever before. In order to exploit these techniques efficiently, chemists must have both an understanding of the techniques' theoretical bases and the ability to interpret the spectra accurately. This workbook presents worked examples and set problems that cover one- and two-dimensional NMR techniques as applied to organic and inorganic systems. Most of the problems are genuine research examples, and this second edition contains numerous new problems derived from recent work, particularly with regard to symmetry and exchange. This new edition is fully compatible with the second edition of Modern NMR Spectroscopy: A Guide for Chemists--the two books are cross-referenced throughout. Students using this book will gain experience in applying advanced NMR techniques in a chemical context and teachers will find it a useful source of new problems and modern examples. For professional scientists, the book provides valuable information which will enable them to use familiar techniques more effectively.

A general disillusionment with conventional medicines, coupled with the desire for a "natural" life style has resulted in an increasing utilization of complementary and alternative medicine (CAM) across the developed world. The global market for herbal products has grown rapidly in the past decade, yet the majority are not assessed for their quality, safety and efficacy. This completely revised and updated edition of Herbal Medicines aims to answer the questions raised for the healthcare professional by providing scientifically rigorous, impartial information on medicinal herbs. It contains: informs on quality, safety and efficacy; offersan overview of UK and European leglisation concerning herbal products; offers an account and examples ofthe scientific methods for investigating the chemical constituents of herbs and for determining their biological activities; deals with 148 herbs commonly present in herbal remedies sold by pharmacies in the UK; enables the healthcare professional to advise the public on the rational and safe use of medicines; and presents various appendices grouping together herbs with specific actions highlighting potential interactions with conventional medicine.

This volume is a potpourri of review articles and research articles related to the "Bioactive Drugs in Drug Discovery and Design". It can be regarded as a continuation volume of the Vol. 22 published by IOS Press in the series of Biomedical and Health Research. Most of the articles are part of the lectures given in the course of "Medicinal Chemistry" for graduate students. The book as the first volume is divided into four different topics in order to help the reader locate easily the manuscript of his interest. The topics which are covered in this book are the synthesis and properties of bioactive molecules and enzymes, the role of membranes in drug activity and formulation, the conformational analysis of bioactive drugs and the molecular targets and drug design.

Machine vision technology has revolutionised the process of automated inspection in manufacturing. The specialist techniques required for inspection of natural products, such as food, leather, textiles and stone is still a challenging area of research. Topological variations make image processing algorithm development, system integration and mechanical handling issues much more complex. The practical issues of making machine vision systems operate robustly in often hostile environments together with the latest technological advancements are reviewed in this volume. Features:
- Case studies based on real-world problems to demonstrate the practical application of machine vision systems.
- In-depth description of system components including image processing, illumination, real-time hardware, mechanical handling, sensing and on-line testing.
- Systems-level integration of constituent technologies for bespoke applications across a variety of industries.
- A diverse range of example applications that a system may be required to handle from live fish to ceramic tiles.
Machine Vision for the Inspection of Natural Products will be a valuable resource for researchers developing innovative machine vision systems in collaboration with food technology, textile and agriculture sectors. It will also appeal to practising engineers and managers in industries where the application of machine vision can enhance product safety and process efficiency.

This manual is intended for the practising chemist who has to do a job in analysing plant material. Therefore, the present manual only contains ready-to-hand procedures without any comment. The procedures described are only for inorganic components, which frequently occur in the plant. Most procedures are designed to give a total content value of the element under consideration, regardless of the chemical structure in which it occurs in the plant.
We have chosen for a design in which all digestion procedures are described in one chapter, all extraction procedures in one chapter and all determination procedures in one chapter. As a consequence, one has to choose a suitable digestion method in combination with the intended determination technique; this has been indicated within each individual determination procedure.
For determination of the elements, mainly spectrometric techniques are used here. Depending on the kind of element and the expected concentration level, the following methods are applied: flame atomic emission spectrometry (flame AES), flame atomic absorption spectrometry (flame AAS), inductively coupled plasma optical emission spectrometry (ICP-OES), electrothermal atomisation (graphite furnace) atomic absorption spectrometry (ETA-AAS), inductively coupled plasma mass spectrometry (ICP-MS), spectrophotometry and segmented flow analysis (SFA). Besides, potentiometry (ion selective electrodes (ISE)) and coulometry will be encountered. In many cases, more than one method is described to determine a component. This provides a reference, as well as an alternative in case of instrumental or analytical problems.

This book is tailored for students and professionals as well as novices from other fields to mass spectrometry. It will guide them from the basics to the successful application of mass spectrometry in their daily research. Starting from the very principles of gas-phase ion chemistry and isotopic properties, it leads through the design of mass analyzers and ionization methods in use to mass spectral interpretation and coupling techniques. Step by step the readers will learn how mass spectrometry works and what it can do as a powerful tool in their hands. The book comprises a balanced mixture of practice-oriented information and theoretical background. The clear layout, a wealth of high-quality figures and a database of exercises and solutions, accessible via the publisher’s web site, support teaching and learning.

This comprehensive and interdisciplinary handbook provides a birds-eye view of two centuries of research on secondary metabolites of the two large Solanales families, Solanaceae and Convolvulaceae. Arranged according to their biosynthetic principles, the occurrence and chemical structures of almost all known individual secondary metabolites are covered, which are found in hundreds of wild as well as cultivated solanaceous and convolvulaceous species. In addition to the biosynthesis, the pharmacological, toxicological, ethnobotanical, ecological, and economic significance of the metabolites is treated. A major aim of this book is the individual phytochemical characterization of the Solanales taxa on the species level. Species are integrated into frameworks of traditional and molecular phylogeny-based classifications. This allows a detailed discussion of chemotaxonomic relationships with regard to all taxon levels up to the order. The text is supplemented by 83 superb color photos of Solanales plants.
