## 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.

Abstract
Complete ^1^H and ^13^C spectral assignments of 17β‐ and 17α‐hydroxy epimers of three biologically active sterols (boldenone, 3‐methoxyestradiol and 3‐methoxydihydroequilenin) were achieved making use of one‐ and two‐dimensional NMR techniques (1D‐HOHAHA, DEPT, COSY, NOESY, TOCSY, HSQC and COLOC).

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 selecti
6-Cadinene from cade oil and ylang-ylang essential oil was independently analyzed by two research groups employing 2D NMR spectroscopy to effect the complete assignment of 'H and "C spectra and to confirm the previously reported structure of S-cadinene.
Three dammarane triterpenoids, cabraleone (20S,24S-eopxy-25-hydroxydammaran-3-one), cabraleadiol (20S,24Sepoxydammarane-3a,25-diol) and shoreic acid (20S,24~-epoxy-25-hydroxy-3,4-secodammar~(28)-en-3-oic acid), were isolated for the first time from the stem bark of Dysoxylum malabaricum Bedd.
