''A wealth of information...these two volumes will be immensely valuable to anyone having to deal with this difficult group of compounds.'' ---Biochemical Systematics and Ecology, from a review of Saponins Used in Traditional and Modern Medicine and Saponins Used in Food and Agriculture
In the plant kingdom a variety of chemical constituents occur in a glycoside form (conjugation with sugar). Glycosides are important, secondary metabolites. The structural diversity is a result of the vast amount of varieties and stereochemical configurations of the sugar component. Aglycones belong to terpenoid, steroid, flavonoid, quinonoid, lignan, other simple phenolics, and isothiocyanate. However, biological activities of glycosides are, in many cases, susceptible to the nature of sugar moieties, even though their aglycone is the same.Since the 80s, plant glycosides have been attracting an increasing volume of interest from botanists and phytochemists world-wide for the following reasons:• They are difficult to isolate and purify• They have a very important biological function in plant life and remarkable biological activities• They are a very important resource of natural medicine, health food, cosmetics and food supplements.The first International Symposium on Plant Glycosides (ISPG), held in Kunming, China was attended by more than 150 scientists from 17 countries. During the four day meeting, 96 reports on plant glycosides, including structure elucidation, ethnobotany, pharmacology, quantitative evaluation, synthesis, pharmacology and biotechnology were presented. 54 of these papers are given in this volume. All these papers review recent research results on plant glycosides.
As in previous volumes, readers will find a multidisciplinary forum for communicating knowledge related to the botany, horticulture, and pharmacology of herbs, spices, and medicinal plants. While magical and mystical powers have been associated with these plants through the ages, continued investigations in such areas as production, nomenclature, uses, chemical constitution, and dynamics help elucidate the affiliated chemical and physical processes that contribute to their unique flavor, fragrance, pharmacological, and other bioactive properties. This collection of articles examines the potential of natural products as pesticides, the richness of the Chinese Pharmacopeia, the similarities of Eastern Asian and Eastern North American medicinal plants, the use of borage as a source of gamma linolenic acid, and the botanical nomenclature of medicinal plants.
This book represents the first comprehensive compilation of information on all aspects of the medicinal plant Panax ginseng, ranging from its botany to applied aspects in medicine and molecular breeding. In contributions by respected experts, it also discusses the genetic background and biochemical profile of this important medicinal plant. Ginsenoside biosynthesis and metabolic dynamics are also described in detail. Given its scope, the book offers a valuable guide for students, educators and scientists in academia and industry interested in medicinal plants and pharmacy.
This book summarizes recent advances in the chemistry, bioactivity, nutrition, and functional aspects of dietary phytochemicals, as well as the health and functional aspects of foods rich in phytochemicals. Consisting of forty-four chapters, it discusses the different chemical types of phytochemicals in our diets and food and presents data collected from animal or human experiments that are directly related to human health. Each chapter covers the chemistry, epidemiological study, bioavailability, bioactivity (animal experiments) function in humans and safety, as well as products on the market. Moreover, the more than 200 figures make it easy to grasp the main findings in each area.
Molecular Basis of Nutrition and Aging: A Volume in the Molecular Nutrition Series focuses on the nutritional issues associated with aging and the important metabolic consequences of diet, nutrition, and health. The book is subdivided into four parts that reflect the impact of nutrition from a biomolecular level to individual health. In Part One, chapters explore the general aspects of aging, aging phenotypes, and relevant aspects of nutrition related to the elderly and healthy aging. Part Two includes molecular and cellular targets of nutrition in aging, with chapters exploring lipid peroxidation, inflammaging, anabolic and catabolic signaling, epigenetics, DNA damage and repair, redox homeostasis, and insulin sensitivity, among others. Part Three looks at system-level and organ targets of nutrition in aging, including a variety of tissues, systems, and diseases, such as immune function, the cardiovascular system, the brain and dementia, muscle, bone, lung, and many others. Finally, Part Four focuses on the health effects of specific dietary compounds and dietary interventions in aging, including vitamin D, retinol, curcumin, folate, iron, potassium, calcium, magnesium, zinc, copper, selenium, iodine, vitamin B, fish oil, vitamin E, resveratrol, polyphenols, vegetables, and fruit, as well as the current nutritional recommendations. - Offers updated information and a perspectives on important future developments to different professionals involved in the basic and clinical research on all major nutritional aspects of aging - Explores how nutritional factors are involved in the pathogenesis of aging across body systems - Investigates the molecular and genetic basis of aging and cellular senescence through the lens of the rapidly evolving field of molecular nutrition
Saponins are complex molecules made up of sugars linked to a triterpenoid or a steroid or a steroidal alkaloid. These natural products are attracting much attention in recent years because of the host of biological activities they exhibit. The diversity of structural features, the challenges of isolation because of their occurrence as complex mixtures, the pharmacological and biological activities still to be discovered, and the prospect of commercialization - these all are driving the study of saponins. Triterpenoid saponins are dominating constituents of this class and occur widely throughout the plant kingdom including some human foods e. g. beans, spinach, tomatoes, and potatoes, and animal feed e. g. alfalfa and clover. Saponins were initially a rather neglected· area of research primarily because of great difficulties in their isolation and characterization. With the advent of more sophisticated methods of isolation and structure elucidation through the last two decades, there has been increased interest in these natural products. Besides structure determination, research activities are now moving forward to clarify structure-activity relationships. Our previous reviews on triterpenoid saponins (l, 2) covered literature from 1979 to mid-1989. The literature on triterpenoid saponins up to 1988 has also been covered by two reviews by HILLER et at. (3, 4). This review incorporates newer trends in isolation and structure determination of triterpenoid saponins, new triterpenoid saponins isolated and biological properties of these products reported during the period late 1989-mid 1996. 2.
