Plant Toxin Analysis

Chemical defence by means of toxins poisonous to other organisms, be they animals or plants, is widespread amongst the plant kingdom - including microorganisms as well. This book embraces the analysis of a wide range of plant toxins and this fills a gap in the plant pathology and ecological biochemistry fields. The topics covered include toxic extracellular enzymes, host selective toxins, elicitors, phototoxins, aflatoxins, mycotoxins, and ecotoxic substance tests by pollen germination and growth. The analytical procedures, which are used to evaluate the toxins, are covered in such a way that the reader is able to carry them out mostly solely by following the detailed descriptions.

Analysis Of Plant Poisons Is A Complete Source Book And Is The First Book Of Its Kind. It Is An Authoritative Textbook That Covers The Broad Gamut Of Forensic Subjects That Span Foresic Toxicology, Forensic Chemistry And Medico Legal Aspects, It Is A Remarkable Accomplishment, Worthwhile And Valuable Addition To The Forensic Literature. The Authors Have Composed An Out Standing Single Volume That Combines A Through Review Of Analysis Of Poisonous Plants In Recent Years Rapid Developments In Phyto Chemistry And Toxicology Expanded The Boundaries Of The Subject. Different Sophisicated Instrumental Analytical Techiques Have Been Introduced In Forensic Analysis. Present Book Provides Alll Such Information'S Needed To Forensic Toxicologist. It Will Also Be A Useful Reference Text For Students And Teacher Of Botany, Chemistry, Pharmacy, Vaterinary Science

Analysis of Food Toxins and Toxicants consists of five sections, providing up-to-date descriptions of the analytical approaches used to detect a range of food toxins. Part I reviews the recent developments in analytical technology including sample pre-treatment and food additives. Part II covers the novel analysis of microbial and plant toxins including plant pyrrolizidine alkaloids. Part III focuses on marine toxins in fish and shellfish. Part IV discusses biogenic amines and common food toxicants, such as pesticides and heavy metals. Part V summarizes quality assurance and the recent developments in regulatory limits for toxins, toxicants and allergens, including discussions on laboratory accreditation and reference materials.

This book presents refereed and edited papers from the 6th International Symposium on Poisonous Plants, held in Scotland in August 2001. It covers a range of topics from plant biochemistry to toxic effects in animals (particularly grazing farmed animals) and humans. The contents include the evolution of antinutrients and toxins in plants, biomedical applications of toxins in plants, isolation, identification and effects of plant and fungal toxins and the effect of plant toxins on aversion to plants in animal diets.

"Natural toxins are compounds that are naturally produced by living organisms. They are not harmful to the organisms themselves but may be toxic when eaten. This book provides an overview of analysis and detection methods of a number of the toxins present in some commonly consumed foods and details the pros and cons of different analysis methods"--

Natural toxins are poisonous secondary metabolites produced by living organisms which are typically not harmful to the organisms themselves but can impact on human or animal health when consumed. Common sources of such toxins include poisonous plants, fungi, algae, and bacteria, and the diversity of these biological systems presents challenges to analytical chemists in identification in addition to wide-ranging food safety implications when present as contaminants in food commodities. The propensity for such toxins to be present in both animal feed and human food has led to the introduction of regulations for a small number of the most potent natural toxins, particularly mycotoxins. Implementation of these regulations necessitates the establishment of high-throughput analytical chemistry methods with increasingly lower limits of detection. The impacts of plant toxins are not limited to grazing livestock but can be carried through the food chain, with some toxins, such as indospicine, being demonstrated to accumulate in tissues of grazing animals, causing secondary poisoning in animals consuming meat from this livestock. This Special Issue focuses on the analysis of natural toxins and their incidence, from source organisms to food and feed commodities, in addition to their implications for food safety.
