Book excerpt: Herbal medicinal products are becoming more widely accepted as alternatives to medical prescriptions. Many physicians believe that herbal medicinal products are able to beneficially complement or even replace chemical medicines. Recognizing this, European institutions are pushing the harmonization of assessment criteria for herbal medicinal products. However, this kind of reevaluation of herbal medicinal products is combined with increased expectations of physicians, pharmacists, and patients with regard to quality, safety and efficacy. There are often uncertainties about the interpretation of basic terms related to the manufacture and quality of herbal medicinal products. Herbal Medicinal Products clarifies these uncertainties, increasing transparency in the herbal medicinal products market and supporting an adequate scientific discussion related to herbal medicinal products. It offers a complete survey on current scientific knowledge, as well as on legal basic requirements for the development, standardization, and licensing of herbal medicinal products.

Download or read book Pyrrolizidine Alkaloids written by Helmut Wiedenfeld and published by Vandenhoeck & Ruprecht. This book was released on 2008 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Plants containing pyrrolizidine alkaloids are so numerous and widespread that they can be expected to be present in most environments. About 200 pyrrolizidine alkaloids have been isolated and identified from different plants. Interest in these alkaloids has increased in recent years due to their causative effects in the heavy loss of livestock in many countries. Naturally Occurring Pyrrolizidine Alkaloids discusses the plant sources and properties of pyrrolizidine alkaloids; extraction, fractionation and identification; various methods of spectrometry of pyrrolizidine alkaloids; quantitative determination; and the toxicity, carcinogenicity, pharmacology, and other biological activities of pyrrolizidine alkaloids. Researchers in veterinary and human medicine will find this book to be a fascinating and useful reference tool.

Available in PDF, EPUB and Kindle. Book excerpt: Inherent toxicants and processing contaminants are bothnon-essential, bioactive substances whose levels in foods can bedifficult to control. This volume covers both types of compound forthe first time, examining their beneficial as well as theirundesirable effects in the human diet. Chapters have been writtenas individually comprehensive reviews, and topics have beenselected to illustrate recent scientific advances in understandingof the occurrence and mechanism of formation, exposure/riskassessment and developments in the underpinning analyticalmethodology. A wide range of contaminants are examined in detail,including pyrrolizidine alkaloids, glucosinolates, phycotoxins, andmycotoxins. Several process contaminants (eg acrylamide and furan),which are relatively new but which have a rapidly growingliterature, are also covered. The book provides a practical reference for a wide range ofexperts: specialist toxicologists (chemists and food chemists),hygienists, government officials and anyone who needs to be awareof the main issues concerning toxicants and process contaminants infood. It will also be a valuable introduction to the subject forpost-graduate students.

Available in PDF, EPUB and Kindle. Book excerpt: In an effort to implement conservation measures farmers have used a variety of production methods, including the use of reduced or zero tillage and cover crops. One benefit of these production methods has been early season weed control. The literature suggests that a variety of mechanisms may be involved, among them the allelopathic effects of phenolic acids. This retrospective analysis addresses the following: How likely are phenolic acid concentrations and environmental conditions in wheat no-till cropping systems for the inhibition of annual broadleaf weed emergence? and Do phenolic acids have a dominant role or are they just one component of a larger promoter/modifier/inhibitor complex? The book covers allelopathic plant-plant interactions, laboratory and field experiments, and future research. It uses a journal format, provides justifications for procedures used, if-then hypotheses, and cons and pros so that readers can reach their own conclusions.
