Abstract: The COLOC-S pulse sequence (modification of COLOC) for obtaining long-range 13C-1H chemical shift correlated spectra was applied to study the structures of oridonin and amethystonal. The results show that the COLOC-S pulse sequence is very useful for structure elucidation and NMR spectra assignments of natural organic compounds.

Key words: Oridonin, Amethystonal, 2D-NMR, COLOC-S
