title: Acyl migration evaluation in monoacylglycerols from Echium plantagineum seed oil and Marinol.
abstract: Production of 2-monoacylglycerols (2-MAGs) by selective hydrolysis of the triacylglycerols (TAGs) of Echium plantagineum seed oil and Marinol and further purification was carried out. Three purification methods, including silica gel column chromatography, liquid-liquid extraction and low-temperature crystallization were assayed. Partial acyl migration during the purification step is always observed. Acyl migration rates were similar both for the column chromatography and for the liquid-liquid extraction methods, and resulted in 1-MAG/2-MAG ratios higher than 1.0. Fatty acid (FA) profiles of 2-MAGs after enzyme hydrolysis showed that the major FAs were stearidonic acid (56.9% of total FA in 2-position) and docosahexaenoic acid (63.6% of total FA in 2-position) for E. plantagineum seed oil and Marinol, respectively.
