## 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.

✦ Synopsis
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.

## Abstract Four sesquiterpene glucosides were isolated from __Ixeris sonchifolia__ Hance. The structure of a new compound (1) was assigned as 9β‐monohydroxy‐2,12‐dioxo‐guaia‐3,11(13)‐dien‐1α,5α,6β,7α,9β,10αH‐12,6‐olide‐9‐__O__‐β‐D‐ glucopyranoside (ixerinoside). In addition, unambiguous and comple
1 H and 13 C NMR spectral data for phytochelatin, NH 3 C --Glu-Cys 2 -Gly-COO , were assigned by a combination of one-( 1 H, 13 C) and two-dimensional (DQF-COSY, CH-COSY, HMBC) NMR experiments.
The indole alkaloid strychnobrasiline was studied using one-and two-dimensional NMR techniques. The interpretation of these spectra led to the complete assignments of all carbon and proton chemical shifts.
