Popis: The detailed analysis of peach seed oil was performed using 1 Hand 13 C NMR spectroscopy.From the 13 C NMR solution spectra it was possible to detect the content of saturated, mostly palmitic fattyacids ( ∼ 100gkg − 1 ), the oleic–linoleic ratio in sn-1,3 and sn-2 positions was (2:1 and 1:2) and the positionaldistribution of glycerol esters on triacylglycerol chains, which is a mixture of OPO and OOP. With thesecharacteristics this oil can be used in food applications.  2005 Society of Chemical Industry Keywords: 13 C NMR; peach oil; characterization; glycerol esters INTRODUCTION Peach ( Prunuspersica Batsch)isawell-knownfruit thatis produced commercially in Brazil and many otherparts of the world.
