Book Description
Pyrrolizidine alkaloids show only minor toxicity in their native state, but are metabolized in the human or animal organisms to carcinogenic, teratogenic and mutagenic compounds, with the precise structure of these compounds being responsible for the metabolic toxification process. Therefore, to be able to evaluate the toxic potential of each alkaloid, it is essential to exactly know the structure of the respective compound. X-ray structure analysis is the appropriate method both for elucidating the structure and for determining other parameters, such as the lengths of the bonds that influence the metabolic process. This book describes the incidence and the process of the intoxication as well as the possibilities to how the substances may reach the organism. In addition, the compounds elucidated by X-ray structure analysis to date are shown in their three-dimensional structure and structure-toxicity relationships are discussed.Pyrrolizidinalkaloide weisen in nativem Zustand nur geringe Toxizität auf, werden jedoch zu kanzerogenen, teratogenen und mutagenen Verbindungen metabolisiert, wenn sie in den menschlichen oder tierischen Organismus gelangen. Der Verlauf dieser Toxifizierung hängt von der konkreten Struktur dieser Stoffe und weiteren Parametern ab. Zur Bestimmung dieser Faktoren stellt die Röntgenstrukturanalyse die geeignete Methode dar. Im vorliegenden Buch werden das Vorkommen, der Ablauf der Toxifizierung und die Möglichkeiten, wie die Stoffe in den Organismus gelangen können, beschrieben. Es werden die bislang durch Röntgenstrukturanalyse vermessenen Verbindungen in ihrer 3D-Struktur aufgefÃ"hrt und Struktur-Toxizitätsbeziehungen diskutiert.

Book Description
This volume contains monographs prepared at the eightieth meeting of the Joint FAO/WHO Expert Committee on Food Additives (JECFA), which met in Rome, Italy, from 16 to 25 June 2015. [Author] The toxicological and dietary exposure monograph in this volume summarizes the safety and dietary exposure data on a contaminant group (pyrrolizidine alkaloids) discussed at the eightieth meeting. [Author] Monographs on seven food additives discussed at that meeting have been previously published in the WHO Food Additives series (FAS 71), and a monograph on a second contaminant group (non-dioxin-like polychlorinated biphenyls) has been published as a separate supplement in the WHO Food Additives series. [Author] This volume and others in the WHO Food Additives series contain information that is useful to those who produce and use food additives and veterinary drugs and those involved with controlling contaminants in food, government and food regulatory officers, industrial testing laboratories, toxicological laboratories and universities.

Book Description
The consumption of herbal products continues to increase, with an estimated sales growth of 10-15% per year projected through the end of the 1990s. As more and more consumers use herbs, it becomes that much more important to ensure that the herbs are used properly and safely. While herbs generally have a safe consumption history, information relevant to specific herbs and particular populations has not been easily available. The Botanical Safety Handbook provides readily accessible safety data in an easy-to-use classification system for more than 600 commonly sold herbs. The handbook also features additional information regarding international regulatory status, standard dosage, and certain common toxicity concerns. The editors of this book are among the most respected leaders in the herbal products industry. Their experience includes years of clinical practice, manufacturing and industry governance, and significant writing and lecturing about herbs. The Botanical Safety Handbook is for manufacturers of herbal products, health professionals who prescribe herbal remedies, and the consumer. This is a valuable resource for the safe dispensation of herbal products, and will help ensure the safe consumption of herbs through the 1990s and beyond.
