This book is an essential reference guide to spectroscopic, physical and biological activity data of over 3500 steroid glycosides, offering the structures and the data of the naturally occurring glycosides of steroids. All compounds are arranged according to the structure of the aglycone, and, in its own class, by the increasing molecular weight, making Spectroscopic Data of Steroid Glycosides extremely useful for the structure elucidation of new natural products, particularly glycosides.

Spectroscopic Data of Steroid Glycosides

Atta-ur- Rahman

Isoquinoline alkaloids represent one of the two largest groups of alkaloids, the other being indole alkaloids. The present volume, which is the third of this series, describes the spectral data of about 700 isoquinoline alkaloids and covers the literature up to 1992. The spectral data of the remaining classes of isoquinoline alkaloids will be published in another volume within a year.The compounds are arranged according to their structural types in various subclasses. Within each subclass they are arranged in order of increasing molecular weight. Compounds in the same subclass and having the same molecular weight are arranged in order of increasing carbon number.The UV, IR, 1 H-NMR and 13 C-NMR 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 1 H-NMR spectral data are presented in ppm and the chemical shifts in the older data published in &tgr values have been converted to &dgr values to ensure uniformity of format. The protons and carbons to which the data refers have been italicised. If any of the data given is that of a salt (e.g. hydrochloride) then this is indicated in brackets before the data. If the compounds are known by more than one name, the older names are given in brackets after the newer one. Spectral data of simple derivatives of compounds are also reported, but only if the data for acetyl, benzoyl, methyl and ethyl derivatives are given. The numbering systems used are given both at the beginning of each sub-class as well as at the end of the book. Compound, molecular formula, molecular weight, plant sources and compound-type indices are also included which should enhance the utility of the book.

Handbook of Natural Products Data: Isoquinoline alkaloids

This volume covers the physical characteristics and spectral data of 1500 pentacyclic triterpenes reported until the end of 1990. 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, 1 H-NMR and 13 C-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 1 H-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. The book will be invaluable for organic chemists, natural product chemists, medicinal chemists and pharmacologists.
