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.
