GC/MS analysis of the oxidation products of fatty acids methyl esters of sunflower oil
Abstract
Oxidation of sunflower oil FAMEs with hydrogen peroxide in the presence of formic acid may be
used in the development of new technologies for production of valuable compounds from the renewable plant
raw materials.
A mixture of the derivatives of the fatty acids methyl esters have been investigated by the GC/MS
method using a capillary column. It has been revealed the presence of large numbers of compounds, with a
prevalence of at least 24 components. 14 oxidation products have been identified by fragmentation from their
individual mass spectra. The main components of the mixture of oxidation FAMEs were methyl 9,10-
epoxyoctadecanoate and methyl 9,10-dihydroxyoctadecanoate.
In summary, the proposed method has proved to be an excellent step to approach the quantitative
analysis of oxidized fatty acids methyl esters of sunflower oil.
