Spectroscopic information of Steroid Glycosides serves as a necessary reference consultant containing spectroscopic, actual and organic job facts of over 3500 steroid glycosides, delivering the constructions and the information of the obviously happening glycosides of steroids. All compounds are prepared based on the constitution of the aglycone, and, in its personal category, in accordance with the expanding molecular weight, making Spectroscopic facts of Steroid Glycosides extremely precious for the constitution elucidation of recent average items, rather glycosides.
Spectroscopic facts of Steroid Glycosides deals a realistic table reference for all scientists and scholars drawn to steroid glycosides and their organic and medicinal importance.
The following information of the steroid glycosides, as to be had in released literature, are included:
- Name of the compound
- Chemical identify of compound and its structure
- Source, identify of the genus, species, authors, relatives of the organic resource from which the glycoside has been isolated.
- Melting point
- Specific rotation
- Molecule weight
- Molecular formula
- UV spectral info : maxima, e or log e , solvent
- IR peaks in cm-1 with medium during which the spectrum used to be taken e.g. KBr, nujol, etc
- Proton magnetic resonance (PMR) chemical shifts, multiplicity of the peaks, coupling constants with assignments
- 13 C-NMR (CMR) chemical shifts with assignments
- Mass spectral info with the process used (e.g. Electron influence (E.I.), quickly Atom Bombardment (FAB), optimistic ion or unfavourable ion mode or the other technique
- CD or ORD data
- Biological Activity
- Full reference from which information were taken
