Application of gradient-enhanced nuclear Overhauser effect spectroscopy GOESY) in the structure elucidation of plant secondary metabolites.

Gradient enhanced nuclear Overhauser effect spectroscopy (GOESY) has been applied in the structural elucidation of five plant secondary metabolites: eucalyptin, arctigenin, 5-geranyloxy-7-methoxycoumarin, 2,6-dihydroxy-4-methoxyisovalerophenone and N-feruloyltyramine. The importance and sensitivity of this technique in structure elucidation of plant secondary metabolites are discussed.
