The I3C 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 "C signals were based on DEPT sequences, two-dimensional (2D) 6H/K NMR spectra and comparison with known compounds.The assignments of some known ent-kaurenes are revised
