Abstract

The ^13^C resonances of ethidum bromide (1), dimidium bromide (2) and 3,8‐diamino‐5‐methylphenanthridinium chloride (3) in D~2~O solution have been assigned. Assignments were made using fully coupled spectra, spectra obtained from a selected 180°‐τ‐90° pulse sequence in conjunction with gated irradiation to obtain NOE intensification, selective proton decoupling, chemical shift arguments and by noting the effect of pD on the ^13^C chemical shifts of 1 and 3.

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-
