摘要：
The C-13 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-13 signals were based on DEPT sequences, two-dimensional (2D) deltaH/deltaC NMR spectra and comparison with known compounds. The assignments of some known ent-kaurenes are revised
