Sažetak
Nuclear magnetic resonance spectroscopy (NMR) is a widespread method for investigation of organic compounds structure including polyphenols. For the identification of polyphenols, the most common NMR technique includes one - dimensional NMR techniques such as 1H and 13C. However, to overcome problems of spectral overlap two- dimensional nuclear magnetic resonance spectroscopy (2D NMR) is used. 2D NMR is a set of NMR methods that gives data plotted in a space defined by two frequency axes rather than one. The most popular two-dimension NMR experiments are the homonuclear correlation spectroscopy (COSY) sequence, heteronuclear single-quantum correlation spectroscopy (HSQC) and heteronuclear two-bond or multiple-bond correlation spectroscopy (H2BC, HMBC, respectively). In this study, the results of eight different polyphenol compounds structure determined by advanced 2D-NMR technique (COSY, HSQC, H2BC, and HMBC) are shown.
