摘要:

AbstractThe13C nuclear magnetic resonance (NMR) spectral data for nineent‐kaurenes, 12ent‐beyeranes and fourent‐atisene derivatives, isolated fromElaeoselinumspecies, are discussed. The assignments of the13C signals were based on DEPT sequences, two‐dimensional (2D) δH/δC NMR spectra and comparison with known compounds. The assignments of some knownent‐kaurenes
