2.2 Experimental methods
EMO and MO required for preparing the standard mixtures for the1H NMR quantification were prepared taking OA as starting material. First, MO was prepared by acid catalyzed esterification of the OA (Scheme 1 ). In second step, the obtained fatty ester was epoxidized resulting in the production of EMO as final product (Scheme 1 ). Both the MO and EMO obtained from the esterification and epoxidation reaction respectively were purified using column chromatography prior to the preparation of standard EMO and MO mixtures.
