Abstract
The 13C 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 13C 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.Keywords
