Spectroscopic Data of Steroid GlycosidesDr. Viqar Uddin Ahmad,HEJ Research Institute of Chemistry, University of Karachi, Karachi, PakistanDr. Anwer Basha,Abbott Laboratories , Abbott Park, Illinois, USASpectroscopic Data of Steroid Glycosides serves as an essential reference guide containing 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, according to 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 offers a practical desk reference for all scientists and students interested in steroid glycosides and their biological and medicinal importance.The following data of the steroid glycosides, as available in published literature, are included:Name of the compound Chemical name of compound and its structureSource, name of the genus, species, authors, family of the biological source from which the glycoside has been isolated.Melting pointSpecific rotationMolecule weightMolecular formulaUV spectral data : maxima, e or log e , solventIR peaks in cm-1 with medium in which the spectrum was taken e.g. KBr, nujol, etcProton magnetic resonance (PMR) chemical shifts, multiplicity of the peaks, coupling constants with assignments13C-NMR (CMR) chemical shifts with assignmentsMass spectral data with the technique used (e.g. Electron Impact (E.I.), Fast Atom Bombardment (FAB), positive ion or negative ion mode or any other techniqueCD or ORD dataBiological ActivityFull reference from which data have been taken
