Amazon.com description: Product Description: The present volume, covers the physical characteristics and spectral data of 971 diterpenoid and steroidal alkaloids reported until the end of 1988. The compounds are arranged according to their chemical structures in various subclasses, and within each subclass they are arranged in order of increasing molecular weight. The UV, IR, ¹H-NMR and ¹³C-NMR and MS spectral data are given in descending orders of magnitude. All &egr; values in the UV spectra have been converted to log &egr;. The chemical shifts in the ¹H-NMR spectral data are presented in ppm and the chemical shifts in older data published in &tgr; values have been converted to &dgr; values to ensure uniformity of format. Data are also presented, where available, on simple derivatives of the alkaloids. CAS Registry Numbers are also given.

The book is thoroughly indexed, containing a compound index, molecular weight index, molecular formula index, compound type index and plant source index, which should greatly facilitate the task of the reader in searching for individual compounds. A section describing the numbering system concludes the volume.

Being the first comprehensive book on natural products which presents the actual spectral data rather than just references to the data, this book should prove of great benefit to organic chemists, natural product chemists, medicinal chemists and pharmacologists.
