✦ Synopsis

After correlation of the majority of signals by COSY and one-bond heteronuclear correlation, the complete assignment of the 'H and I3C NMR spectra of the macrolide antibiotic venturicidin A required the application of long-range CH coupling information. This was accessible by the COLOC-S and selective INEPT experiments, and the sensitivity of these experiments is discussed. Steric information was obtained from a NOESY spectrum, and the solution structure compared with that in the crystal.

## Abstract A tricyclic sesquiterpene ketone, patchoulenone, was isolated from the hexane extract of the root bark of __Uvaria narum__ Wall. (Annonaceae). Its structural elucidation was based on detailed 2D NMR spectroscopy, leading to the complete assignment of the ^1^H and ^13^C NMR spectra.
