• Resumen

  • High-resolution NMR spectra of selective 1D, 2D homonuclear and 2D heteronuclear experiments were registered of the mixtures of the natural products 3-4 and the methyl esters (5-6) and acetyl derivates (7-8) of the natural product 1-2, using Pulsed Field Gradients (PFGs) technique. Thus, it was possible to obtain high-resolution spectra, smaller time of acquisition and larger structural information
