Several two-dimensional NMR techniques were applied to assign completely the ' H and 13C chemical shifts and to study the configuration and conformation of a new triterpenoid, 3-keto-9,10,19cyclopropyllanost-24-en-26-oic acid (ganwuweizic acid). Some 13C NMR signals previously reported for the trite

✦ Synopsis
The controversy about the 13C NMR assignment of the methyl groups in angelates and tiglates was settled by two-dimensional 'H-=C chemical shift correlations for angelic and tiglic acid.

## Abstract The ^1^H and ^13^C NMR spectra of eledoisin, an antidiuretic hormone, were studied by two‐dimensional NMR techniques. All the ^1^H and ^13^C NMR resonances were unambiguously determined from a combination of the 2D homo‐ and hetero‐nuclear NMR spectra.
The complete assignment of the 13C and 'HNMR spectra of sipholenol-A and sipholenone-A, two new triterpenes isolated from a marine sponge, were achieved from 'H-OC shift correlation diagrams.
