dc.description.abstractThis work extends previous research regarding the role of (esterified) steryl glucosides ¿(E)SG- in olive oil. In line with previous research and to contribute to a comprehensive olive oil chemical characterization, we have determined the profile and content of these compounds in different mono-variety virgin olive oils using cholesterol ß-D-glucoside (ChSG) as single internal standard. To do this, we have collected 22 types of olive cultivars, extracted the oils by the Abencor® method and applied a formerly developed SPE protocol. We have also determined the corresponding response factors with respect to the internal standard. Additionally, we have analyzed some of the purity and quality parameters included in the Regulations with the aim of understanding their relationship with those sterol derivatives. Results show the feasibility of using ChSG as internal standard, shortening the global time of analysis. They also confirm the suitability of the limits previously established for the presence of ESG in olive oil (0.2 ¿ 14.0, but almost double those for SG (up to 4.77 Data also indicates the lack of a direct, stoichiometric relationship between some possible substrates (sterols, free fatty acids and related compounds) and the products -(E)SG-. Future lines of research are therefore outlinedpt_BR
