Quadrupole time-of-flight mass spectrometry analysis of glycerophospholipid molecular species in the two halophyte seed oils: Eryngium maritimum and Cakile maritima
چکیده انگلیسی
Future applications of lipids in clinical cohort studies demand detailed glycerophospholipid molecule information and the application of high-throughput lipidomics platforms. In the present work, a novel sensitive technique with high mass resolution and accuracy was applied to accomplish phospholipid analysis. Nanospray ionization quadrupole time-of-flight mass spectrometry was used to separate and quantify the glycerophospholipid classes as well as molecular species in two halophyte seed oils from Cakile maritima and Eryngium maritimum. Precursor or neutral loss scans of their polar head groups allowed the detection of molecular species within particular glycerophospholipid classes. Phosphatidylcholine was found to be the most abundant glycerophospholipid in both seed oils whereas phosphatidylethanolamine and phosphatidic acid were less abundant. Phosphatidylinositol, phosphatidylserine and phosphatidylglycerol were minor glycerophospholipids. Several molecular species within each class were detected and the main molecular species (C36:4, C36:3, C36:2, 34:2 and C34:1) were quantitatively different between the two halophytes and the different glycerophospholipids.
