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.

Krone der Schöpfung? Vor 100 000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies, und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70 000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens, und es war vor allem die Beschaffenheit seines Gehirns, die ihn zum Herren des Planeten und zum Schrecken des Ökosystems werden ließ. Bis heute hat sich diese Vorherrschaft stetig zugespitzt: Der Mensch hat die Fähigkeit zu schöpferischem und zu zerstörerischem Handeln wie kein anderes Lebewesen. Anschaulich, unterhaltsam und stellenweise hochkomisch zeichnet Yuval Harari die Geschichte des Menschen nach und zeigt alle großen, aber auch alle ambivalenten Momente unserer Menschwerdung.

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.

The quality control of herbal drugs is alsobecoming essential to avoid severe health problems, and in thefuture many more new drugs will be developed from plantsources. This three-volume Handbook, featuring 47 detailed review articles,is unique as it deals with chemical and biological methodologiesfor plant analysis. It presents the most important and mostaccurate methods which are available for plant analysis. This comprehensive work is divided into six sections asfollows: Sample preparation and identification – discussingplant selection and collection, followed by extraction and samplepreparation methodologies. Extraction and sample preparation methodologies Instrumentation for chemical analysis - severalinstrumentations for chemical plant analysis are presented with anemphasis on hyphenated techniques, e.g. the coupling between HPLCand mass spectroscometry, and HPLC with NMR. Strategies for selective classes of compounds –coverage of the most interesting classes of compounds such aspolysaccharides, saponins, cardiotonic glycosides, alkaloids,terpenoids, lipids, volatile compounds and polyphenols (flavonoids, xanthones, coumarins, naphthoquinones, anthraquinones,proanthocyanidins, etc.). Biological Analysis - includes phenotyping, DNA barcodingtechniques, transcriptome analysis , microarray, metabolomics andproteomics. Drugs from Plants – covers the screening of plantextracts and strategies for the quick discovery of novelbioactive natural products.

Edited by two of the experts in the field, the central aim is to show organic chemists working in process development that enantioselective catalysis is suitable for the large-scale production of enantioenriched intermediates. In so doing, it is equally a source of information and inspiration for academic research, and, with its contribution by Noble prizewinner W. S. Knowles, will also heighten the status of industrial catalyst specialists working in the exciting field of enantioselective catalysis. Some 25 contributions from top industrial researchers around the world present case studies on the development of the widest possible range of large-scale enantioselective processes, featuring stereoselective production processes of fine-chemicals, agrochemicals and pharmaceuticals. Clearly structured according to the nature of the task, this handbook adopts a problem-driven approach such that readers can easily find how colleagues have dealt with a similar situation.
