Abstract
The ^1^H and ^13^C NMR spectra of methyl (−)‐zanzibarate (1), an ent‐labdanic diterpene isolated from the epicarp of Hymenaea courbaril var. altissima (Leguminosaea, Cesalpinoideae, Detariae), was fully assigned by COSY experiments, ^13^C/^1^H shift correlation diagrams and NOE experiments.

The 1H and 13C NMR spectra of glucodigifucoside and glucogitoroside, cardenolides isolated from Digitalis lanata leaves, were completely assigned with the aid of 2D homonuclear (COSY) and heteronuclear (HETCOR and HMQC) correlation spectra. 1997
H and =CNMR spectra of the novel marine macrolide swinholide-A, which provide the basis for its structure elucidation, have been completely assigned by parallel use of 1D and homo-and hetero-nuclear 2D NMR techniques. Swinholide-A (1) probably a polyketide, is a 22-membered macrolide embodying a dih
