The 13C assignment of four indole alkaloids of deformyl corymine type, isolated from Winchia carophylla, is reported. The effects of the substituents have been discussed. Due to the very similar environment of some carbon nuclei, the signals of them were identified by a hetero-nuclear C-H shift correlated spectrum or a selective decoupling technique.

Key words: C13 NMR SPECTROMETRY, INDOLE ALKALOIDS, CHEMICAL SHIFT, SUBSTITUENT EFFECT
