Notes:
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.
