Abstract: Calonyctin A which was extracted from leaves of Calonyction aculeatum (L.) House was discovered being not a single component. We extracted the sample from Calonyction aculeatum (L.) House then separated by HPLC and got two major components denominated as DC-2b and DC-2d.
In this paper, the structure of DC-2b was determined by 13C-NMR, DEPT, SELECTIVE INEPT, 2D 1H-COSY, 2D 13C-1H COSY and 2D-NOESY techniques.

Key words: Calonyctin A, NMR, Structure
