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.
