Pattern-Type Separation of Triacylglycerols by Silver Thiolate×Non-Aqueous Reversed Phase Comprehensive Liquid Chromatography

Triacylglycerols (TAGs), as the main components of edible oils and animal fats, are responsible for nutritional value, organoleptic features technological properties foods; each lipid matrix shows a unique TAG profile which can serve fingerprint to ensure quality authenticity food products. The high complexity many foodstuffs often makes untargeted elucidation challenging task; thus, more efficient separation techniques may be mandatory. In this research, borage (Borago officinalis) seed oil was obtained by two-dimensional comprehensive liquid chromatography (LC×LC), coupling silver thiolate octadecylsilica monodisperse materials. A total 94 compounds were identified ion trap-time flight detection, using atmospheric pressure ionization, with degree unsaturation varying from 0 9, partition values ranging 36 56. group-type afforded analytical approach useful quickly samples.
