Abstract
A quantitative method was established to determine the presence and co mposition of mono-, di-, and triglycerides of olive oils of superior g rade via C-13 NMR. The total diglyceride content and the ratio of sn-1 ,2- and sn-1,3-diglycerides in extra virgin oils extracted from differ ent alive cultivars were correlated with maturity. The correlation can be applied to identify the oils by variety. No monoglycerides were de tected in the oils examined.
