The lipid fraction of wheat of different species (TA = Triticum aestivum an
d TD = Triticum durum), varieties, origin and year of production was extrac
t and analysed. The gas chromatographic analysis was performed by using FID
and mass spectrometry as a highly sensitivity detector, with very low nois
e. The chromatograms showed the presence of an average of 60 peaks. Most of
the compounds (not less than 92%) were identified and determined.. Fatty a
cids with carbon atoms even numbers from C-12 to C-30, C-15 and C-17 were f
ound. The major components of the fat were saturated and unsaturated C-16 a
nd C-18. Squalene and a consistent sterol fraction (about 2%) were present,
as well. Differences among varieties, species and origin were found and di
scussed.
