Abstract:

Seven monomeric compounds from pecan (Carya illinoensis) oil were separated and identified by preparative
high performance liquid chromatography with evaporative light scattering detection combined with mass spectrometry
(HPLC-ELSD-MS). All these compounds were confirmed as triglycerides by comparison of their NMR and MS data with
those of authentic standards or literature data, namely trilinolein, dilinolein, 1,2-dilinoleoyl-3-palmitoyl-rac-glycerol,
dioleoylglycerol, 1-palmitin-2-olein-3-linolein, glycerol trioleate, dioleoyl 2-palmitoyl triglyceride, respectively.

Key words: Carya illinoensis oil, separation and identification, triacylglycerols
