The Dictionary of Natural Products is the only comprehensive source of chemical data on natural products. It provides the busy scientist with fast access to chemical, physical, bibliographic, and structural data on over 139,000 natural products organized into more than 43,000 -virtually every natural product isolated and reported in the literature.

A vast array of natural organic compounds, the products of primary and secondary metabolism, occur in plants. This dictionary provides basic information, including structural formulae, on plant constituents. It profiles over 3000 substances from phenolics and alkaloids through carbohydrates and plant glycosides to oils and triterpenoids. For each substance, the author presents the trivial name, synonyms, structural type, chemical structure showing stereochemistry, molecular weight and formula, natural occurrence, biological activity and commercial or other use. Key references are provided for each class and subclass.

A dictionary of natural products. This fourth supplementary volume includes new and updated entries. It should be of interest to natural product chemists and bioscientists. Also available as a substructure searchable CD-ROM.

A unique collection of concise but detailed information on 10,000 animals, plants, fungi and algae of the British Isles. Every species with an English common name is included. The compendium is in two parts. The first, smaller part, looks at various terms that people interested in natural history may come across. The second provides information on individual species or species groups, with entries on those with English (common) names, as well as selected families, orders, classes, etc. In the case of marine organisms, entries are given for intertidal and subtidal invertebrate species, and generally speaking for fish species that might be observed inshore. Indication is often given on distribution as well as whether a species is common, scarce or something in between. For some species a note is made of population size and trends. Comments are made where appropriate on etymology, both of the English name and the binomial. No other natural history dictionary or cognate publication relating to the British Isles is as comprehensive in taxonomic cover.

This first supplement to the "Dictionary of Natural Products" main work (Volume 8 of DNP) contains the structures, bibliographies and physical properties of 3,000 compounds, grouped within approximately 2,000 entries, and updating the coverage to mid-1993.

Containing fully authenticated data on virtually all known natural products, the Dictionary of Natural Products, main work, published in 1993 was the end result of over 12 years compilation and editing by a large team of contributors and the editorial staff of the Chapman & Hall Scientific Data Division. The resulting Dictionary contains 100,000 natural products and their derivatives organized into approximately 35,000 entries.

The Dictionary of Food Ingredients is a unique, easy-to-use source of infor mation on over 1,000 food ingredients. Like the previous editions, the new and updated Third Edition provides clear and concise information on currently used additives, including natural ingredients, FDA-approved artificial ingredients, and compounds used in food processing. The dictionary entries, organized in alphabetical order, include information on ingredient functions, chemical properties, and uses in food products. The updated and revised Third Edition contains approximately 1 SO new entries, and includes an updated and expanded bibliography. It also lists food ingredients ac cording to U. S. federal regulatory status. Users of the two previous editions have commented favorably on the dictionary's straightforward and clearly-written definitions, and we have endeavored to maintain that standard in this new edition. We trust it will continue to be a valuable reference for the food scientist, food processor, food product developer, nutritionist, extension specialist, and student. R S. Igoe Y. H. Hui vii Ingredients A Acacia See Arabic. Acesulfame-K A non-nutritive sweetener, also termed acesulfame potas sium. It is a white, crystalline product that is 200 times sweeter than sucrose. It is not metabolized in the body. It is relatively stable as a powder and in liquids and solids which may be heated. Acesulfame-K is approved for use in dry food products. Acesulfame Potassium See Acesulfame-K.

Natural products chemistry-the chemistry of metabolite products of plants, animals and microorganisms-is involved in the investigation of biological phenomena ranging from drug mechanisms to gametophytes and receptors and drug metabolism in the human body to protein and enzyme chemistry. Introduction to Natural Products Chemistry has collected the
