This comprehensive treatise offers an in-depth discussion of natural toxicants in plants, emphasizing their effects as defenses against herbivory. Coevolution of plants and her-bivores are covered with a detailed treatment of toxicant metabolism and systemic effects in mammalian tissues. Con-sideration of the economic importance of plant toxins, modi-fication by plant breeding, management of toxico-sis, and toxicant problems in various geographic areas are in-cluded. Each volume offers an extensive description of chemistry, biosynthesis, analysis, distribution in plants, metabolism in mam-mals and insects, and practical problems in humans and livestock.

Most of the non-nutrient chemicals humans ingest with their normal diet are naturally occurring secondary metabolites of food plants. Quantitatively, exposures to these plant-specific constituents may significantly exceed dietary exposures to most of the synthetic chemicals, which may intentionally or unintentionally occur in food. Some of them have been shown to be highly potent toxins. It has been proposed to define inherent plant toxicants as plant constituents, which might induce adverse effects in humans when the plant or plant products are consumed. Examples are glycoalkaloids in potatoes, cyanogenic glucosides in cassava or phytohemaglutinin in red kidney beans. They have all been causally associated with acute human toxicity when ingested through foods that were not properly processed or prepared. Both toxicological and exposure data are limited for most inherent plant toxicants. Therefore, accurate risk assessment is often not possible. For many inherent toxicants the margin of exposure between toxic levels in humans and actual exposure from food is low. Therefore risk management measures need to be implemented in order to ensure food safety. Management options include development of cultivars low in inherent toxicants, agricultural and storage practices, and food processing. Further work is necessary to better characterize the potential health impact of inherent plant toxicants. This should include the development of a risk assessment paradigm which considers both potential adverse but also beneficial effects of secondary plant metabolites and of the pertinent food plants as such.

In Volume 1 of this series, attention was focused on neuropoisons of animal origin. In the present volume, attention has been shifted to poisons of plant origin. In both cases, we have attempted to identify those poisons for which there is a large measure of clinical or research interest. Our efforts in compiling the series have been aided by three groups of individuals. First, we are grateful to the investigators who contributed chapters. Their labors are the substance of this two-volume work. Second, we are pleased to acknowledge the support of Mr. Seymour Weingarten and Plenum Press in our project. And third, we have been immeasurably aided by our assistants, Mrs. Ruby Hough in New York City and Mrs. Helena Walsh in Canberra. To all these persons, we are indebted. Dr. Lance L.

This volume reviews current knowledge of toxic substances in crop plants with particular reference to their anti-nutritional effects in animals and man and the potential for detoxification. The distribution and ecological significance of these compounds is also addressed. Continuing disquiet over the use of animal by-products in livestock nutrition has provided renewed impetus for the greater exploitation of conventional and novel crop plants both as food and as industrial raw materials. However, a major factor restricting the utilisation of such crops in animal nutrition is the presence of a diverse array of toxic substances capable of inducing effects ranging from loss of hair and wool to severe neurological disorders and even death. Significant advances have been made to establish the nature of these compounds and to assess their effects in animals and man. As in other branches of biomedical research, these developments have been achieved through the multidisciplinary efforts of chemists, biochemists, toxicologists, nutritionists and molecular geneticists. This volume reviews current knowledge of toxic substances in crop plants with particular reference to their anti-nutritional effects in animals and man and the potential for detoxification. The distribution and ecological significance of these compounds is also addressed.
