本文报道了四个deformyl corymine 的吲哚生物碱的^1^3C谱的归属, 对一些取代基效应进行了讨论; 并应用了C-HCOSY及选择去偶技术, 指认^1^3C信号。

关键词: 碳13核磁共振谱法, 吲哚生物碱, 化学位移, 取代基效应

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
