Abstract Phosphitylation of the free hydroxyl and carboxyl groups of a series of polyphenol-containing virgin olive oil model compounds with 2-chloro-4,4,5,5-tetramethyl-dioxaphospholane allows their detection on the basis of the 31P-NMR chemical shifts. Unambiguous assignment of the 31P-NMR chemical shifts of the dihydroxy- and polyhydroxy-phenols has been achieved by employing a number of two-dimensional NMR techniques. Furthermore, integration of the appropriate signals of the hydroxyl derivatives in the corresponding 31P-NMR spectra allows the quantification of these compounds. This study demonstrates the potential of 31P-NMR spectroscopy for the qualitative and quantitative analysis of polyphenols in virgin olive oils.
