Sesame (Sesamum indicum L.) is a global oil crop. Sesame oil has been regarded as functional
oil with antioxidant properties in several in vivo studies but little is known about its minor fraction.
In this line, this study figures out the profile of the polar fraction of Egyptian cultivar Giza 32 sesame
oil (SG32 oil) employing reversed-phase high-performance liquid chromatography coupled with
diode array detection and electrospray ionization-quadrupole-time-of-flight-mass spectrometry
and tandem MS. The characterization of the sesame oil metabolites depended on the observation
of their retention time values, accurate MS, and MS/MS data, with UV spectra, and compared
with relevant literature and available standards. Remarkably, 86 metabolites were characterized
and sub-grouped into phenolic acids, lignans, flavonoids, nitrogenous compounds, and organic
acids. From the characterized metabolites, 72 compounds were previously characterized in SG32
cake, which presented antioxidant properties, and hence it could contribute to SG32 oil antioxidant
properties. Further studies are required to state the presence of such phenolics in commercial sesame
oils and what of these compounds resist oil refining.
