Abstract

The carbon‐13 NMR spectra of lanosta‐8‐en‐3β‐ol, lanosta‐8, 24‐dien‐3β‐ol, lanosta‐7,9(11)‐dien‐3β‐ol, lanostan‐3β‐ol, eupha‐8‐en‐3β‐ol, eupha‐8,24‐dien‐3β‐ol, ursa‐12‐en‐3β‐ol (α‐amyrin) and oleana‐12‐en‐3β‐ol (β‐amyrin) have been obtained and completely assigned. The results of this study provide chemical shift data for methyl, methylene, methine and quaternary carbon atoms in tetra‐ and pentacyclic triterpenoid spectra. The carbon‐13 NMR spectrum of a triterpenoid provides a unique fingerprint for the molecule.

## Abstract Carbon‐13 signal assignments of the labdane diterpenoids phlogantholide‐A, its diacetate and isophlogantholide‐A are reported. The assignments of the ^13^C NMR signals of 14‐deoxyandrographolide and its diacetate, made earlier, have now been confirmed by lanthanide shift studies on the
