Download or read book Natural Products Isolation written by Satya D. Sarker and published by Springer Science & Business Media. This book was released on 2008-02-05 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Microwave assisted Extraction for Bioactive Compounds written by Farid Chemat and published by Springer Science & Business Media. This book was released on 2012-12-12 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: With increasing energy prices and the drive to reduce CO2 emissions, food industries are challenged to find new technologies in order to reduce energy consumption, to meet legal requirements on emissions, product/process safety and control, and for cost reduction and increased quality as well as functionality. Extraction is one of the promising innovation themes that could contribute to sustainable growth in the chemical and food industries. For example, existing extraction technologies have considerable technological and scientific bottlenecks to overcome, such as often requiring up to 50% of investments in a new plant and more than 70% of total process energy used in food, fine chemicals and pharmaceutical industries. These shortcomings have led to the consideration of the use of new "green" techniques in extraction, which typically use less solvent and energy, such as microwave extraction. Extraction under extreme or non-classical conditions is currently a dynamically developing area in applied research and industry. Using microwaves, extraction and distillation can now be completed in minutes instead of hours with high reproducibility, reducing the consumption of solvent, simplifying manipulation and work-up, giving higher purity of the final product, eliminating post-treatment of waste water and consuming only a fraction of the energy normally needed for a conventional extraction method. Several classes of compounds such as essential oils, aromas, anti-oxidants, pigments, colours, fats and oils, carbohydrates, and other bioactive compounds have been extracted efficiently from a variety of matrices (mainly animal tissues, food, and plant materials). The advantages of using microwave energy, which is a non-contact heat source, includes more effective heating, faster energy transfer, reduced thermal gradients, selective heating, reduced equipment size, faster response to process heating control, faster start-up, increased production, and elimination of process steps. This book will present a complete picture of the current knowledge on microwave-assisted extraction (MAE) of bioactive compounds from food and natural products. It will provide the necessary theoretical background and details about extraction by microwaves, including information on the technique, the mechanism, protocols, industrial applications, safety precautions, and environmental impacts.

Download or read book Preparative Chromatography Techniques written by K. Hostettmann and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past few years, increasing attention has been paid to the search for bioactive compounds from natural sources. The success of plant-derived products such as paclitaxel (Taxol) in tumor therapy or artemisinin in the treatment of malaria has provided the impetus for the introduction of numerous research programmes, especially in Industry. A great deal of effort is being expended in the generation of novel lead molecules of vegetable, marine and microbial origin by the use of high throughput screening protocols. When interesting hits are found, it is essen tial to have methods available for the rapid isolation of target compounds. For this reason, both industry and academia need efficient preparative chromatographic separation techniques and experience in their application. Purified natural products are required for complete spectro scopic identification and full characterization of new compo unds, for biological testing and for the supply of pharmaceuti cals, standards, and starting materials for synthetic work. Obtaining pure products from an extract can be a very long, te dious and expensive undertaking, involving many steps. Sometimes only minute amounts of the desired compounds are at hand and these entities may be labile. Thus it is an advantage to have access to as many different methods as possible in order to aid the isolation process. Although a certain amount of trial and error may be involved, nowadays there is the possibility of devising suitable rapid separation schemes by a judicious choice of the different techniques available.
