The term “natural products” spans an extremely large and diverse range of chemical compounds derived and isolated from biological sources. Our interest in natural products can be traced back thousands of years for their usefulness to humankind, and this continues to the present day. Compounds and extracts derived from the biosphere have found uses in medicine, agriculture, cosmetics, and food in ancient and modern societies around the world. Therefore, the ability to access natural products, understand their usefulness, and derive applications has been a major driving force in the field of natural product research. The first edition of Natural Products Isolation provided readers for the first time with some practical guidance in the process of extraction and isolation of natural products and was the result of Richard Cannell’s unique vision and tireless efforts. Unfortunately, Richard Cannell died in 1999 soon after completing the first edition. We are indebted to him and hope this new edition pays adequate tribute to his excellent work. The first edition laid down the “ground rules” and established the techniques available at the time. Since its publication in 1998, there have been significant developments in some areas in natural product isolation. To capture these developments, publication of a second edition is long overdue, and we believe it brings the work up to date while still covering many basic techniques known to save time and effort, and capable of results equivalent to those from more recent and expensive techniques.

A book intended for organic chemists, food scientists, geo-chemists, materials science researchers, and entomologists. Since the publication of the first edition, natural product research technology has advanced through the fields of chemistry, food science, geochemistry, materials science, and entomology. Comparisons of these compounds in micro-organisms, algae, animals, higher plants and marine invertebrates are now documented. With the advent of such techniques as Raman spectroscopy, magic-angle spinning spectroscipy, high-resolution electron microscopy and X-ray crystallography, separation of isomers, positional isomers, regioisomers, stereoisomers, and even isotopic isomers are possible.

Eukaryotic cells are remarkably complex structures, containing a vast repertoire of macromolecules, organelles, and other compartments that orchestrate the tasks required for life. For in-depth studies of their function and composition, reliable methods for the isolation of specific subcellular structures are often required. This laboratory manual provides step-by-step protocols for the extraction of subcellular components from animal tissues, yeasts, plants, and cultured cells. Each chapter focuses on a particular eukaryotic organelle, vesicle, membrane, or macromolecular complex. Strategies for breaking cells while maintaining the structural and functional integrity of the component of interest, enriching for that component based on its physical and biochemical characteristics, and monitoring and ensuring the success of the purification procedure are provided. The contributors describe both traditional approaches (e.g., density gradient centrifugation) and innovative techniques (e.g., the use of SPIONs) for isolating subcellular constituents. This manual is therefore an essential laboratory resource for all cell biologists seeking a comprehensive collection of dependable subcellular fractionation methods.

Recent major shifts in global health care management policy have been instrumental in renewing interest in herbal medicine. However, literature on the development of products from herbs is often scattered and narrow in scope. Herbal Bioactives and Food Fortification: Extraction and Formulation provides information on all aspects of the extraction of biological actives from plants and the development of dietary supplements and fortified food using herbal extracts. The book begins with a brief survey of the use of herbs in different civilizations and traces the evolution of herbal medicine, including the emergence of nutraceuticals from the discipline of ethnopharmacology and the Alma Ata Declaration of 1978. It moves on to describe various aspects of the extraction process, including selection of plant species, quality control of raw materials, the comminution of herbs, and the selection of solvents. It also describes the optimization of extraction in relation to response surface methodology before describing uses of herbal extracts in food supplements and fortified foods. With special attention paid to stability analysis and the masking of tastes, the book gives an overview of the formulation of various types of tablets, capsules, and syrups using herbal extracts. It also describes the benefits of foods fortified with herbal extracts such as soups, yogurt, sauces, mayonnaise, pickles, chutneys, jams, jellies, marmalades, cheese, margarine, sausages, bread, and biscuits, as well as some beverages. Herbal Bioactives and Food Fortification covers the fundamental steps in herbal extraction and processing in a single volume. It explains how to choose, optimize, analyze, and use extracts for fortification, making it an excellent source for nutraceutical researchers and practitioners in science and industry.
