This book presents a collection of known information on the insecticidal properties of constituents of higher plants, microorganisms, animals, and marine flora and fauna in order to assist researchers in selecting leads for further development.

A compilation of all the known information on terpenoids specifically triterpenoids, is presented in these volumes. The most important available information on a particular compound is discussed, such as its isolation/occurence, available spectral data, and leading references on structural determination. Additionally, triterpenoids synthesis, biosynthesis, proven pharmacological properties, and any known applications are explained. A comprehensive general introduction has been included which surveys the development of triterpenoid chemistry from the beginning to the present. Extremely helpful is the selected list of references to books and reviews dealing with various aspects of triterpenoid chemistry.

This Handbook, pinpoints salient features of known information about Terpenoids in a readily accessible and readable format. Terpenoids have singularly enriched organic chemistry by its variety of structural types, by its wealth ofunexpected reactions, rearrangements and spectral features, and by offering exciting targets for synthesis. Much imaginative experimental work has been invested in exploring their natural pathways. Recent years have revealed an increasingly important biological and ecological role for several of its members.
