Analyse des lipides et autres composés volatils de Deglet Nour, cultivar de palmier dattier (Phoenix dactylifera L.), par chromatographie en phase gazeuse couplée à la spectrométrie de masse

Abstract

Chemical analysis of volatile compounds of roots and palms (leaflets) of Phoenix dactylifera L. is described here for the first time. Fifty four molecules are detected by gas chromatography (GC) coupled with mass spectrometry (MS), forty one of them are identified. Roots contain forty one volatile substances (97.2%), seventeen from them are fatty acids (50.7%) with methyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate predominance (24.9%). Twenty three volatile components (99.1%) occur in palms; nine are fatty acids (45.7%) which the most abundant are the iso—palmitic acid (13.8%) and the 1,3,5-benzene tricarboxylic acid, trimethyl ester (13%). In addition to fatty acids and their methyl esters, date palm organs contain various other classes of volatile organic compounds. The date palm, plants with great economic importance through its fruit, could be through its vegetative organs, a considerable potential source of interesting natural organic substances in various fields.
