Book Description
The presence of contaminant flavonoids in vitamin C preparations from citrus fruits initially led Szent-Gyorgyi and his collaborators to suggest that a flavonoid compound, with biological activity for the prevention of capillary fragility, was vitamin P. Later re search, although not disproving biological activity, discontinued the use of the vitamin classification for these compounds. However, the ubiquitous distribution of flavonoids in living organisms, and the continued discovery of various activity in biological systems makes these compounds targets of wide ranging investigation. This volume is primarily based on a Symposium on Flavonoids and related com pounds held during the 212th National Meeting of the American Chemical Society held in Orlando, Florida on August 28-29, 1996 under the sponsorship of the Division of Agricul tural and Food Chemistry. While the book is not intended to be a comprehensive volume on flavonoid research, the papers provide various approaches to exploring the biological functions of flavonoids in plants and animals, their chemical modifications for enhanced activity, some analytical techniques, as well as their use in food classification. A signifi cant portion is devoted to medicinal implications of these compounds. The organizers would like to express their appreciation to Tropicana Products, Inc., Bradenton, Florida, Coca-Cola Foods Division, Plymouth, Florida and the American Chemical Society's Division of Agricultural and Food Chemistry for financial support. Of course, the book could not be produced without the authors, whose cooperation and pa tience is greatly appreciated.

Book Description
The discovery of biological activity associated with flavonoid contaminants in vitamin C preparations from bell peppers and lemons by Szent-Gyorgyi and his associates opened a floodgate of research into the biological functions of this ubiquitous and diverse group of compounds. Since then, a broad range of physiological and biochemical activities were discovered in living systems including most plants and animals. With the continued discovery, isolation and identification of new natural and synthetic compounds exhibiting biological activities, entire research programs are devoted to wide ranging investigations to nearly every conceivable area, from microbial and plant interaction, growth regulation and development to physiological, genetical, medicinal actions and uses in animals. This volume is based on presentations made at a Symposium, titled Flavonoids in Cell Function, held during the 219'h National Meeting of the American Chemical Society held in San Francisco, California on March 29-30, 2000. The book is not intended to be a comprehensive treatise on flavonoid research, only a sampling of recent results. The papers cover a range of topics discussing various approaches to flavonoid study, starting at plant microbe communication through analytical methods to medicinal and systemic implications of these compounds in animal cells and systems. The organizers would like to express their thanks to Cargill Foods, Inc., Minneapolis, Minnesota and the Division of Agricultural and Food Chemistry of the American Chemical Society for financial support. A great deal of thanks is also due to the authors without whose cooperation and patience this volume would not be realized.

Book Description
Polyphenols: Mechanisms of Action in Human Health and Disease, Second Edition describes the mechanisms of polyphenol antioxidant activities and their use in disease prevention. Chapters highlight the anti-inflammatory activity of polyphenols on key dendritic cells, how they modulate and suppress inflammation, and how they are inactivated or activated by metabolism in the gut and circulating blood. Polyphenols have proven effective for key health benefits, including bone health, organ health, cardiac and vascular conditions, absorption and metabolism, and cancer and diseases of the immune system. They are a unique group of phytochemicals that are present in all fruits, vegetables and other plant products. This very diverse and multi-functional group of active plant compounds contain powerful antioxidant properties and exhibit remarkable chemical, biological and physiological properties, including cancer prevention and cardio-protective activities. Expands coverage on green tea, cocoa, wine, cumin and herbs Outlines their chemical properties, bioavailability and metabolomics Provides a self-teaching guide to learn the mechanisms of action and health benefits of polyphenols

Book Description
Flavonoids are ubiquitously present in plant-based foods and natural health products. The molecule of flavonoids is characterized by a 15-carbon skeleton of C6–C3–C6, with the different structural configuration of subclasses. The major subclasses of flavonoids with health-promotional properties are the flavanols or catechins (e.g., epigallocatechin 3-gallate from green tea), the flavones (e.g., apigenin from celery), the flavonols (e.g., quercetin glycosides from apples, berries, and onion), the flavanones (e.g., naringenin from citrus), the anthocyanins (e.g., cyanidin-3-O-glucoside from berries), and the isoflavones (e.g., genistein from soya beans). Scientific evidence has strongly shown that regular intake of dietary flavonoids in efficacious amounts reduces the risk of oxidative stress- and chronic inflammation-mediated pathogenesis of human diseases such as cardiovascular disease, certain cancers, and neurological disorders. The physiological benefits of dietary flavonoids have been demonstrated to be due to multiple mechanisms of action, including regulating redox homeostasis, epigenetic regulations, activation of survival genes and signaling pathways, regulation of mitochondrial function and bioenergetics, and modulation of inflammation response. The role of flavonoids on gut microbiota and the impact of microbial metabolites of flavonoids on optimal health has begun to unravel. The complex physiological modulations of flavonoid molecules are due to their structural diversity. However, some flavonoids are not absorbed well, and their bioavailability could be enhanced through structural modifications and applications of nanotechnology, such as encapsulation. This Special Issue consists of four review articles on flavonoids and 15 original research articles, which cover the latest findings on the role of dietary flavonoids and their derivatives in disease prevention and treatment.
