Book Description
In recent years, the role of plant secondary metabolites as protective constituents in the human diet has been a growing area of research. Unlike the traditional vitamins, they are not essential for short-term wellbeing, but there is increasing evidence that modest long-term intakes can have favourable impacts on the incidence of cancers and many chronic diseases, including cardiovascular disease and type II diabetes, which are occurring in Western populations with increasing frequency. This book covers the latest science on the metabolism and potential health benefits of teas, cocoa, coffee and their extracts in the human diet. From an opening chapter tracing the origins of teas, cocoa and coffee as beverage, the book proceeds to explore the phytochemical content of coffee, cocoa and the various types of tea. The bioavailability of secondary metabolites from each of the beverages is then considered in depth, and related directly to their health benefits. Embracing the full range of tea, coffee and cocoa beverages and products, the book offers the most up-to-date and comprehensive treatment of these increasingly important dietary components. As the only book to bring together the latest information on the biochemistry and health benefits of teas, coffee and cocoa, this book is essential reading for food scientists and technologists involved in the production of tea, coffee and cocoa products. Nutritionists will value the book's health focus, while agricultural scientists working on the cultivation of these crops will prize its scope and depth of detail. It is also an important resource for all those who use functional ingredients in other products, whether they are based in industry or research.

Book Description
Secondary metabolites are organic compounds that are not directly involved in the normal growth, development, or reproduction of an organism. The secondary metabolites are produced majorly by plants and are called phytochemicals, also by microbes such as bacteria, fungi, algae and so on. These secondary metabolites plays a major role in defensive mechanism in plants, as well as its components are used in food industry, pharmaceuticals and so on. The applications and sources of each secondary metabolite is clearly discussed. We are very much thankful for the publisher who readily accepts and publish this subject. Also the author is very much thankful to her research team Mridul Umesh, Thazeem Basheer, Poorna Chandrika Sabapathy, Sabarinathan Devaraj and Sathishkumar Swamiappan for contributing their help and support for this work. The next edition of this book will more precisely discuss on the extraction and purification of the secondary metabolites.

Book Description
Food security and the medicinal needs of billions of people around the world are pressing global issues, and the biodiversity and sustainable utilization of plants is of great significance in this context. Further, ethnobotanical studies are vital in the discovery of new drugs from indigenous medicinal plants, and plants with industrially important metabolites need to be cultivated to meet the growing market demand. In addition, the production of plant metabolites under in vitro conditions also has tremendous possibilities. The totipotency of plant cells plays a valuable role in the sustainable utilization of plant resources through cell, tissue and organ culture. At the same time, production can be enhanced using productive cell lines, treatment with elicitors, changing nutritional parameters and metabolic engineering. This book provides state-of-the-art information on biodiversity, conservation, ethnobotany, various aspects of In vitro secondary metabolite production, bioprospecting from various plant groups and drug discovery. It also discusses methods of extracting and characterizing drug leads from plant sources.​

Book Description
Plant secondary metabolites have been a fertile area of chemical investigation for many years, driving the development of both analytical chemistry and of new synthetic reactions and methodologies. The subject is multi-disciplinary with chemists, biochemists and plant scientists all contributing to our current understanding. In recent years there has been an upsurge in interest from other disciplines, related to the realisation that secondary metabolites are dietary components that may have a considerable impact on human health, and to the development of gene technology that permits modulation of the contents of desirable and undesirable components. Plant Secondary Metabolites: Occurrence, Structure and Role in the Human Diet addresses this wider interest by covering the main groups of natural products from a chemical and biosynthetic perspective with illustrations of how genetic engineering can be applied to manipulate levels of secondary metabolites of economic value as well as those of potential importance in diet and health. These descriptive chapters are augmented by chapters showing where these products are found in the diet, how they are metabolised and reviewing the evidence for their beneficial bioactivity.

Book Description
Plant secondary metabolism is an economically important source of fine chemicals, such as drugs, insecticides, dyes, flavours, and fragrances. Moreover, important traits of plants such as taste, flavour, smell, colour, or resistance against pests and diseases are also related to secondary metabolites. The genetic modification of plants is feasible nowadays. What does the possibility of engineering plant secondary metabolite pathways mean? In this book, firstly a general introduction is given on plant secondary metabolism, followed by an overview of the possible approaches that could be used to alter secondary metabolite pathways. In a series of chapters from various authorities in the field, an overview is given of the state of the art for important groups of secondary metabolites. No books have been published on this topic so far. This book will thus be a unique source of information for all those involved with plants as chemical factories of fine chemicals and those involved with the quality of food and ornamental plants. It will be useful in teaching graduate courses in the field of metabolic engineering in plants.

Book Description
The chief purpose of such new editions is to bring the text up to date. This I have tried to do. The danger with such endeavours is that the book becomes corpulent. This I have tried to avoid. In so doing I am evermore conscious of how much material has had to be omitted. As before the references (ca. 770 of them) which are cited are intended in part to provide the reader with access to material that has been omitted. I am deeply grateful to Mrs Marjorie Romanowicz for preparing the typed manuscript for this edition with customary accuracy and efficiency, to my wife Margaret for checking the references, and to research students Karl Cable, Lucy Hyatt, Mashupye Kgaphola and Andrew Knaggs for helping with the checking of the manuscript. Richard Herbert April 1988 Preface to the first edition This is a book about experiments and results of experiments. The results described are the fruit of thirty years' labour in the field of secondary metabolism. Secondary metabolism, more than any other part of the chemistry of life, has been the special preserve of organic chemists. Investigation of secondary metabolism began with curiosity about the structures of compounds isolated from natural sources, i.e. secondary metabolites. Coeval with structure determination there has been a curiosity about the origins and mechanism of formation of secondary metabolites (or natural products as they have been called). It is the experimental outcome of this curiosity that is described here.

Book Description
The secondary metabolites of plants were once considered to be waste products - today, their true value is understood. New methods of separation and structural elucidation, and advances in the investigation of biochemical activities, have increased our understanding of secondary metabolites. Their function as a defense mechanisms offers a great potential for technological gain. Secondary metabolites can be utilized in agriculture to breed stronger crops and in the manufacture of biorational pesticides. They can also be exploited by medicine as theraputic agents. And these are just two of the likely uses. This landmark volume presents articles by an impressive team of experts from leading laboratories. Each chapter considers a current understanding of secondary metabolites in nature and the potential exploitation of those qualities by the biotechnology industry.
