The 13 C nuclear magnetic resonance (NMR) spectral data for nine ent ‐kaurenes, 12 ent ‐beyeranes and four ent ‐atisene derivatives, isolated from Elaeoselinum species, are discussed. The assignments of the 13 C signals were based on DEPT sequences, two‐dimensional (2D) δH/δC NMR spectra and comparison with known compounds. The assignments of some known ent ‐kaurenes are revised.
