Abstract

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.

Key words: Tritcrpene, Chemical shift, Assignment, 2D NMR
