Published: December 2009

The (13)C NMR spectra of over 24 tetracyclic triterpenoid derivatives have been structurally analyzed. The (13)C NMR chemical shifts allow one to probe the steric topology of the rigid steroid skeleton and inductive effects of its substituents. Use of deuterium labeling in chemical shift assignment and B-ring aromatic terpenoids are also featured.
