Dieses Buch geht auf eine Vorlesung an der Universität Heidelberg zurück und richtet sich in erster Linie an Studenten, aber auch an Hochschuldozenten, Chemielehrer und Industriechemiker. Es vermittelt Einblicke in die moderne Naturstoffchemie und die Entwicklung komplexer Moleküle (asymmetrische und heterozyklische Verbindungen, polyzyklische Strukturen, makrozyklische und kleine Ringe) in der chemischen Industrie. Ein wichtiges Anliegen des Autors besteht darin, exemplarisch zu belegen, welche Aspekte eine Rolle spielen, wenn man im technischen Maßstab komplexe Verbindungen "auf elegantem Weg" herstellen will. So lernt der Leser die Grundlagen, die für einen jungen Chemiker in der chemischen Industrie unentbehrlich sind. Das Buch deckt ein breites Spektrum von Naturstoffen oder davon abgeleiteten Substanzen ab, darunter Farbstoffe wie etwa Indigo, in der Nahrungsmittelindustrie verwendete Verbindungen wie Coffein, Vanillin, Carotenoide und Aminosäuren, Arzneimittel wie Antibiotika, Opioide, Lipstatin und Steroide, Agrochemikalien wie Herbizide, Fungizide und Insektizide oder auch Duftstoffe wie Moschus und Damascon. Jedes Kapitel liefert auch historische und soziale Hintergrundinformationen zu dem jeweiligen Naturstoff und beschreibt seine biologische Aktivität, seine Entdeckung und seine wichtigsten Modifikationen durch die industrielle Chemie. In vielen Fällen wird die industrielle Synthese mit der Biosynthese verglichen. Überdies beleuchtet das Buch moderne Aspekte und zukünftige Entwicklungen in der Naturstoffsynthese. Ohne auf jeden industriell hergestellten Naturstoff einzugehen - was angesichts der Fülle der Substanzen in einem Lehrbuch auch gar nicht möglich ist -, bietet das verständlich geschriebene Werk einen guten Überblick über das gesamte Gebiet. Dabei kommt die "grüne Chemie" ebenso zur Sprache wie die Atomökonomie und "Eleganz" in der industriellen Naturstoffsynthese.

Natural Products, broadly defined as high value chemical entities derived from plants or microbial sources, have been known and exploited for many years. In recent years, as the need for higher potency and predictability of such products has increased, more sophisticated concentration and isolation procedures have been developed. With the passage of time, such procedures have been rationalized in terms of scientific principles but, in general, theory has followed behind practice, leading at any given time to an absence from the literature of methods which are truly state of the art. Downstream Processing of Natural Products: A Practical Handbook is a highly practical manual which addresses this issue, and guides researchers and industrial workers through the many potential pitfalls of natural product isolation. The contributors to this volume, all of whom have wide practical experience in this field, present state-of-the-art techniques and observations. The three main stages of natural product purification are covered, namely product release, capture, and purification, and both proteins and secondary metabolites are covered. There is special mention of the requirements of the regulatory authorities with respect to Good Manufacturing Practice, and practical guidance is given on scale-up procedures and process scale instrumentation. Downstream Processing of Natural Products: A Practical Handbook will provide essential practical guidance to all those involved in natural product isolation. This includes academic and industrial researchers, postgraduate students and technicians working in the biotechnology field.

Long used in sacred ceremonies and associated with good health, the nutritional and health promoting benefits of olives and olive oils have been proven by an ever-increasing body of science. From cardiovascular benefits to anti-microbial, anti-cancer, antioxidant activity and effects on macrophages and aptoptosis to cellular and pathophysiollogical process, olives and olive oils are proving important in many healthful ways. For example, reactive components in olive oils or olive oil by-products have now been isolated and identified. These include tyrosol, hydroxytyrosol, 3,4-dihydroxyphenyl acetic acid elenolic acid and oleuropein. Oleic acid is the main monosaturated fatty acid of olive oil. These have putative protective effects and modulate the biochemistry of a variety of cell types including those of the vascular system. Some but not all components have been characterised by their putative pharmacological properties. It is possible that usage of these aforementioned products may have beneficial application in other disease. However, in order for this cross-fertilization to take place, a comprehensive understanding of olives and olive oils is required. Finding this knowledge in a single volume provides a key resource for scientists in a variety of food an nutritional roles. Key Features: * Explores olives and olive oil from their general aspects to the detailed level of important micro-and micronutrients * Includes coverage of various methodologies for analysis to help scientists and chemists determine the most appropriate option for their own studies, including those of olive-related compounds in other foods * Relates, in a single volume resource, information for food and nutritional chemists, pharmaceutical scientists, nutritionists and dieticians * Presents information in three key categories: General aspects of olives an olive oils; Nutritional, pharmacological and metabolic properties of olives and olive oil; Specific components of olive oil and their effects on tissue and body systems

Supercritical fluids which are neither gas nor liquid, but can be compressed gradually from low to high density, are gaining increasing importance as tunable solvents and reaction media in the chemical process industry. By adjusting the pressure, or more strictly the density, the properties of these fluids are customized and manipulated for the particular process at hand, be it a physical transformation, such as separation or solvation, or a chemical transformation, such as a reaction or reactive extraction. Supercritical fluids, however, differ from both gases and liquids in many respects. In order to properly understand and describe their properties, it is necessary to know the implications of their nearness to criticality, to be aware of the complex types of phase separation (including solid phases) that occur when the components of the fluid mixture are very different from each other, and to develop theories that can cope with the large differences in molecular size and shape of the supercritical solvent and the solutes that are present.
