Book Description :

Polyphenols in Plants: Isolation, Purification and Extract Preparation, 2nd edition, provides a detailed insight into polyphenols that occur naturally in plants and how they can be affected during growth and development, then effectively removed and optimized for various applications in food production. Historically, plants have been the major sources for drugs and health promotion. While there are a small number of nutrients contained, the growing focus is on the very diverse, complex ring structures: polyphenols that are not nutritious. In order to study or use them in patient treatment, the polyphenols need to be isolated, identified, and purified for application and study. This book brings together experts in the field who share their ongoing examination of isolation and purification of polyphenols as well as determination of their structures and composition. Polyphenols in Plants covers a range of new topics including polyphenols in vegetable waste and agricultural byproducts, extraction methods and characterization of polyphenols, and isolation techniques in the development of new compounds and their use in cancer therapy. This book will be useful to plant scientists and dietary supplement producers, as well as scientists in the food industry and alternative medicine who are interested in the specific health benefits of various dietary extracts and other polyphenol resources. Fully revised and updated to present the latest developments in the field Advances understanding of isolation, characterization, and identification of critical polyphenols vital to industrial development as therapies Defines conditions of growth affecting polyphenol levels Describes techniques critical to identifying and defining polyphenols

Book Description :

Polyphenols are plant non-nutrient natural products, or plant secondary metabolites, found in fruits, vegetables and seeds that we consume daily. Their intakes from fruit, vegetables, seeds, and nuts are associated with lower risks of chronic and age-related degenerative diseases. Aging is a dynamic and complex biological process involving multiple actors and subject to a number of genetic and/or environmental influences. The famous free radical theory of aging proposed by Prof. Harman in 1956 states that free radicals lead to oxidative damage, causing cellular dysfunction and physiological decline, and are responsible for aging, with the appearance of degenerative diseases and eventually death. From this hypothesis, antioxidant molecules are capable of slowing down the aging process through the successful scavenging of radical oxygen and nitrogen species. Polyphenols have been shown to prolong the lifespan of different model species operating through a well-conserved antioxidant mechanism. This collection of research and review articles covers the most recent advances in the use of plant polyphenols, ranging from their biological properties and possible functions as medicines, the importance of traditional medicines as a source of inspiration, the rationalization of new uses of plant extracts which lead to applications in modern medicine, the status of modern green-chemistry extraction methods, to some reflections on future prospects.

Book Description :

This book is the first of its kind that focuses on the chemistry and biology of ellagitannins, a special class of naturally occurring polyphenols which have so far not received the attention they deserve. These polyphenolic substances are found in many plants, including numerous food sources. They not only exhibit unique structural features that fascinate most chemists who are aware of their existence, but also express remarkable biological activities that have yet to attract the interest of the pharmaceutical industry. This is surprising because ellagitannins have been identified as active principles in traditional Chinese medicines. The principal aim of this book is to set the record straight. Most, if not all, worldwide experts in each aspect of the chemistry and biology of this underestimated class of natural products have contributed to this book. It covers topics such as their structural determination and natural occurrence; the most up-to-date knowledge of their biosynthesis; the current state of the art of their total chemical synthesis; their main physicochemical properties and principal biological activities; their presence in food and beverages; and their related health effects. All together, nine chapters compose this book whose content is placed into historical perspective in a yet inspiring preface written by one of the pioneers in modern polyphenol research, Professor Edwin Haslam. This book will be useful not only to scientists involved in natural product research, but also to lecturers and their students as a source of key references and/or a textbook.

Book Description :

Some plants found in the southern part of Africa called resurrection plants have evolved the remarkable ability to survive long periods without water to reach an air-dry state. They occur in a vast area from Namibia in the west to Zimbabwe in the east and parts of South Africa in the south. Many studies have been devoted to study their mechanism of desiccation tolerance. It has been proposed that these plants possess a high level of polyphenols that might be involved in their surviving low water content. Few studies have been done to elucidate the polyphenol content and the chemical structure(s) of the main polyphenol(s) present. This book represents the first such study to characterise the main polyphenols present in these plants and to determine their involvement in desiccation tolerance. This book present data suggesting that though polyphenols contribute to desiccation tolerance and protects cells against desiccation and also against free radical-induced damage, they are not the major determinants. This book is compact enough to serve the graduate student as an introduction to resurrection plants and to the investigator as a quick update on important recent discoveries.

“Antioxidant Activity of Polyphenolic Plant Extracts” is a collection of scientific articles regarding polyphenols, that is, substances occurring naturally in plants and exhibiting many beneficial effects on human health. Among polyphenols’ interesting biological properties, their antioxidant activity is considered the most important. This book brings together experts from different research fields on topics related to polyphenols, such as their isolation and purification, assessment of their antioxidant activity, prevention from oxidative stress-induced diseases and use as food additives. The polyphenols used in the present studies are derived from a great variety of plants, ranging from well-known species to rare ones that are only found in specific regions. Moreover, some of the studies provide evidence that polyphenols may be used for the prevention and treatment of common diseases such as diabetes mellitus, Alzheimers’ disease, cardiovascular and intestinal diseases. Importantly, in several of the studies “green extraction methods” for the isolation of polyphenols were developed using modern technologies, where few or no organic solvents were used, in order to minimize environmental and health impacts.

Book Description :

Plant polyphenols are considered among the most abundant phytochemicals that are present in human diets, and their regular consumption has been associated with reduced risk of a number of chronic diseases, including cancer, and cardiovascular and neurodegenerative disorders. In the past decades, plant polyphenols have drawn increasing scientific attention due to their potent antioxidant and other properties and their marked effects in the prevention of various oxidative stress-associated diseases. Recently, the polyphenolic extracts from different plants have become a major area of health- and medical-related research. This review provides an update and comprehensive overview of various plant polyphenolic compounds, and the quantification of their antioxidant properties, anticancer activities, and therapeutic effects. Also, the review discusses the current scientific knowledge of various plant polyphenols to inhibit tumorigenesis in animal models and to modulate cell signaling pathways involved in inflammation and the development of malignant tumors, and related biochemical interventions in cell function under both normal and pathological conditions. We present in vitro and in vivo studies (in experimental animals) in which polyphenols showed increased anticancer potential. Also, numerous epidemiological research data and findings from human intervention studies, as well preclinical studies supporting cancer prevention mechanisms. Lastly, we present recent clinical trials for anticancer action of certain polyphenols that showed promising anticancer and therapeutic properties.
