13C-NMR Spectral Analysis of Rhazine, Quebrachamine and Rhazinilam1

Abstract
The carbon shifts of the indole alkaloids rhazine and quebrachamine, and the artefact rhazinilam, isolated from Rhazya stricta Decaisne have been recorded. Assignment of chemical shifts to individual carbon atoms has been made; this provides additional support for the constitutions of these compounds.
