New Natural Products and Plant Drugs with Pharmacological, Biological or Therapeutical Activity


Book Description

The fact that, of the approximately 600,000 plant species existing on the earth, only some 5 % have been specifically investigated chemically or pharmacologi cally, is a challenge to chemists spezializing in na tural substances and to pharmacologists. In view of the limited number of research capacities and the ever diminishing financial means, this challenge can only be met if, together with an improvement and refinement of methods of analysis, medicinal plant research is carried out on a broader interdisciplinary basis, with comparable, scientifically recognized screening methods, and if it is better coordinated, with greater use of modern documentation means. It is thus necessary in the future to concentrate specifically on projects leading to the development of new medicinal prepara tions. The plenary lectures hold in the present symposium of the 1st International Congress for Research on Medi cinal Plants reflect these efforts and tendencies. At the same time they provide a survey of some of the fields of medicinal plant research which are at present most actual and most intensively researched. They range from plant screening, isolation and structure eluci dation of new principles, to the therapeutical opti mization of a natural product. The lectures given at this congress show clearly the necessity, in addition to national phytochemical so cieties, for a central international organisation, in which all active medicinal plant researchers in the world are included. Their aim should be to provide the impulse for more optimal, rational research, aimed at the solution of specific projects.

Advanced Pharmacological Uses of Medicinal Plants and Natural Products


Book Description

A vast majority of the world’s population lacks access to essential medicines and the provision of safe healthcare services. Medicinal plants and herbal medicines can be applied for pharmacognosy, or the discovery of new drugs, or as an aid for plant physiology studies. In recent years, there has been increased interest in the search for new chemical entities and the expression of resistance of many drugs available in the market has led to a shift in paradigm towards medicinal research. Herbal treatments, the most popular form of folk medicine, may become an important way of increasing access to healthcare services. Advanced Pharmacological Uses of Medicinal Plants and Natural Products provides emerging research exploring the theoretical and practical aspects of drug discovery from natural sources that allow for the effective treatment of human health problems without any side effects, toxicity, or drug resistance. Featuring coverage on a broad range of topics such as ethnobotany, therapeutic applications, and bioactive compounds, this book is ideally designed for pharmacologists, scientists, ethnobotanists, botanists, health researchers, professors, industry professionals, and health students in fields that include pharmaceutical drug development and discovery.




Pharmacognosy


Book Description

Pharmacognosy is a term derived from the Greek words for drug (pharmakon) and knowledge (gnosis). It is a field of study within Chemistry focused on natural products isolated from different sources and their biological activities. Research on natural products began more than a hundred years ago and has continued up to now with a plethora of research groups discovering new ideas and novel active constituents. This book compiles the latest research in the field and will be of interest to scientists, researchers, and students.




Natural Products and Drug Discovery


Book Description

Natural Products and Drug Discovery: An Integrated Approach provides an applied overview of the field, from traditional medicinal targets, to cutting-edge molecular techniques. Natural products have always been of key importance to drug discovery, but as modern techniques and technologies have allowed researchers to identify, isolate, extract and synthesize their active compounds in new ways, they are once again coming to the forefront of drug discovery. Combining the potential of traditional medicine with the refinement of modern chemical technology, the use of natural products as the basis for drugs can help in the development of more environmentally sound, economical, and effective drug discovery processes. Natural Products & Drug Discovery: An Integrated Approach reflects on the current changes in this field, giving context to the current shift and using supportive case studies to highlight the challenges and successes faced by researchers in integrating traditional medicinal sources with modern chemical technologies. It therefore acts as a useful reference to medicinal chemists, phytochemists, biochemists, pharma R&D professionals, and drug discovery students and researchers. - Reviews the changing role of natural products in drug discovery, integrating traditional knowledge with modern molecular technologies - Highlights the potential future role of natural products in preventative medicine - Supported by real world case studies throughout




The Constituents of Medicinal Plants


Book Description

Pengelly's user friendly text will encourage educators in medical science to consider using this material in the complementary medicine/nutraceuticals areas May I congratulate Andrew Pengelly for writing this text as it is going to be very popular with undergraduate students as well as more experienced readers.' D. Green, London Metropolitan University, UK This unique book explains in simple terms the commonly occurring chemical constituents of medicinal plants. The major classes of plant constituents such as phenols, terpenes and polysaccharides, are described both in terms of their chemical structures and their pharmacological activities. Identifying specific chemical compounds provides insights into traditional and clinical use of these herbs, as well as potential for adverse reactions. Features include: * Over 100 diagrams of chemical structures * References to original research studies and clinical trials * References to plants commonly used throughout Europe, North America and Australasia. Written by an experienced herbal practitioner, The Constituents of Medicinal Plants seriously challenges any suggestion that herbal medicine remains untested and unproven, including as it does hundreds of references to original research studies and trials. Designed as an undergraduate text, the first edition of this book became an essential desktop reference for health practitioners, lecturers, researchers, producers and anyone with an interest in how medicinal herbs work. This edition has been extensively revised to incorporate up-to-date research and additional sections, including an expanded introduction to plant molecular structures, and is destined to become a classic in the literature of herbal medicine.




Natural Products Isolation


Book Description

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.




Development of Plant-Based Medicines: Conservation, Efficacy and Safety


Book Description

The `plant' is often the most neglected part of plant-based medicine. Throughout time, humans have searched, collected, and effectively used plants for healing. Currently, the medicinal plant-based business is flourishing at a dramatic pace and at the expense of an already declining population of plant species, many of which are on the verge of extinction. In spite of this history and popularity, the mystery of what transforms a plant into a medicinal plant persists, and there are chronic problems with ensuring the safety and efficacy of medicinal plant products. Therefore, there is a real need for a full characterization of medicinal plant species and for the development and application of novel technologies for the production of plant-based medicines. This book highlights some of the recent advances and new approaches to the development of technologies for plant-based medicines and is intended to stimulate new discussions among researchers, regulatory authorities, and pharmaceutical organizations, leading to significant advancements in the field.
