The detailed analysis of peach seed oil was performed using 1 H and 13 C NMR spectroscopy. From the 13 C NMR solution spectra it was possible to detect the content of saturated, mostly palmitic fatty acids (∼100 g kg −1 ), the oleic–linoleic ratio in sn‐1,3 and sn‐2 positions was (2:1 and 1:2) and the positional distribution of glycerol esters on triacylglycerol chains, which is a mixture of OPO and OOP. With these characteristics this oil can be used in food applications. Copyright © 2005 Society of Chemical Industry
