摘要：

The detailed analysis of peach seed oil was performed using H-1 and C-13 NMR spectroscopy. From the C-13 NMR solution spectra it was possible to detect the content of saturated, mostly palmitic fatty acids (similar to 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. (c) 2005 Society of Chemical Industry.
