This laboratory manual will be welcomed by all research scientists involved in the extraction, fractionation and isolation of compounds from natural materials, especially those working with plants. The book is clear and concise, and features practical exercises to illustrate the techniques described in every chapter. It will provide an invaluable research reference tool for those scientists investigating the potential benefits of ethnomedicine and the properties of chemicals isolated from natural flora.
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.

Research studies demonstrate diet and proper nutrition in conjunction with cognitive, mental, social, and physical activities can significantly help in improving brain health with advancing age, and potentially reduce the risk of cognitive decline. These studies of phytopharmaceuticals and medicinal plants, demonstrate the efficacy of Huperzine A, berry anthocyanins, trans-resveratrol, Ginkgo biloba, Bacopa monniera, Centella asiatica, tocotrienols, and palm oil in boosting brain health and physical well-being. In addition, consumption of marine fishes and general seafood is recommended for long-term nutritional intervention to preserve mental health, hinder neurodegenerative processes, and sustain cognitive capacities in humans. Omega-3 and omega-6 polyunsaturated fatty acids, n-3/n-6 PUFAs, flavonoids, and antioxidants prevent the initiation and progression of many neurological disorders. This book is a comprehensive review of phytopharmaceuticals impacting brain health with emphasis on diverse applications in food and nutrition sciences, biomedicine, neurology and other scientific and medical fields. It details available methods and contains numerous references making this the perfect guide for scientists who want to explore the fascinating world of phytopharmaceuticals with relation to brain health. Phytopharmaceuticals for Brain Health appeals to a diverse range of readers in industry, medical doctors, research and academia, including biologists, biochemists, food scientists, nutritionists and health professionals. Overall, this book brings a classic scenario of neurological problems to possible amelioration using novel nutraceuticals and functional foods.
This Encyclopedia of Biotechnology is a component of the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Biotechnology draws on the pure biological sciences (genetics, animal cell culture, molecular biology, microbiology, biochemistry, embryology, cell biology) and in many instances is also dependent on knowledge and methods from outside the sphere of biology (chemical engineering, bioprocess engineering, information technology, biorobotics). This 15-volume set contains several chapters, each of size 5000-30000 words, with perspectives, applications and extensive illustrations. It carries state-of-the-art knowledge in the field and is aimed, by virtue of the several applications, at the following five major target audiences: University and College Students, Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers and NGOs.
This volume is a laboratory companion to the author's book Chemistry of Natural Products: A Unified Approach (Universities Press, 1999). Chemistry of natural experimentation. Though there is much good source material on the theoretical aspects of the subject, the average undergraduate and postgraduate student remains unexposed to the large amount of published experimental details of isolation......
Quality Control and Evaluation of Herbal Drugs brings together current thinking and practices for evaluation of natural products and traditional medicines. The use of herbal medicine in therapeutics is on the rise in both developed and developing countries and this book facilitates the necessary development of quality standards for these medicines.This book elucidates on various challenges and opportunities for quality evaluation of herbal drugs with several integrated approaches including metabolomics, chemoprofiling, marker analysis, stability testing, good practices for manufacturing, clinical aspects, Ethnopharmacology and Ethnomedicine inspired drug development. Written by Prof. Pulok K Mukherjee, a leader in this field; the book highlights on various methods, techniques and approaches for evaluating the purity, quality, safety and efficacy of herbal drugs. Particular attention is paid to methods that assess these drugs' activity, the compounds responsible and their underlying mechanisms of action. The book describes the quality control parameters followed in India and other countries, including Japan, China, Bangladesh, and other Asian countries, as well as the regulatory profiles of the European Union and North America. This book will be useful in bio-prospecting of natural products and traditional medicine-inspired drug discovery and development. - Provides new information on the research and development of natural remedies - essential reading on the study and use of natural resources for preventative or healing purposes - Brings together current thinking and practices in quality control and standardization of herbal drugs highlighting several integrated approaches for metabolomics, chemo-profiling and marker analysis - Aids in developing knowledge of various techniques including macroscopy, microscopy, HPTLC, HPLC, LC-MS/MS, GC-MS etc. with the development of integrated methods for evaluation of botanicals used in traditional medicine - Assessment of herbal drugs through bio-analytical techniques, bioassay guided isolation, enzyme inhibition, pharmacological, microbiological, antiviral assays and safety related quality issues - References global organizations, such as the WHO, USFDA, CDSCO, AYUSH, TCM and others to serve as a comprehensive document for enforcement agencies, NGOs and regulatory authorities
This encyclopedic reference work on pharmacognosy covers the study of those natural substances, principally plants, that find a use in medicine. Its popularity and longevity stem from the book's balance between classical (crude and powdered drugs' characterization and examination) and modern (phytochemistry and pharmacology) aspects of this branch of science, as well as the editor's recognition in recent years of the growing importance of complementary medicines, including herbal, homeopathic and aromatherapy. No other book provides such a wealth of detail. A reservoir of knowledge in a field where there is a resurgence of interest - plants as a source of drugs are of growing interest both in complementary medicine fields and in the pharmaceutical industry in their search for new 'lead compounds'. Dr Evans has been associated with the book for over 20 years and is a recognised authority in all parts of the world where pharmacognosy is studied, his knowledge and grasp of the subject matter is unique. Meticulously referenced and kept up to date by the editor, new contributors brought in to cover new areas. New chapter on 'Neuroceuticals'. Addition of many new compounds recently added to British Pharmacopoeia as a result of European harmonisation. Considers development in legal control and standardisation of plant materials previously regarded as 'herbal medicines'. More on the study of safety and efficacy of Chinese and Asian drugs. Quality control issues updated in line with latest guidelines (BP 2007).
