| Abstract: | The structural analysis of compound (1) was carried out using NMR. Several methods ,including 1H-1H two-dimensional shift correlation spectroscopy, 13C-1H two-dimensional shift correlation spectroscopy, COLOC (Correlation spectroscopy via LOng rang Coupling) and DEPT were used for chemical assignment. This investigation demonstrates the power of two - dimensional NMR techniques in the structural determination of natural products. |
