โฆ Synopsis
The 1H and 13C NMR spectra of baccharis oxide, a common triterpene in many Baccharis species, were assigned unambiguously by CรC correlations (2D-INADEQUATE).

## Abstract A computerized analysis of a single 2D INADEQUATE spectra assigns all of the ^13^C chemical shifts in fairly complex aromatic systems. Without the aid of the computer this information is often difficult, if not impossible, to retrieve owing to overlap of the signals in the double quantu
Three known bisabolane hydrocarbons, a-trans -bergamotene, sesquiphellandrene and zingiberene, were isolated from the aerial parts of Alpinia densibracteata . Their 1H and 13C NMR spectra were completely assigned by using a combination of 13C DEPT and 2D-NMR experiments (1H-1H COSY, single-bond 13C-
