Glyceride studies: Part IX: Intraglyceride distribution of vernolic acid and of five conjugated octadecatrienoic acids in seed glycerides

Abstract

Vernolic (epoxyoleic) acid, present in six seed oils over the range 19-72%, appears to be preferentially attached to the secondary glycerol hydroxyl group. The distribution of five isomeric conjugated octadecatrienoic acids (8, 10, 12 and 9, 11, 13) in 18 seed oils has been examined by lipase-catalyzed deacylation. The results are not entirely consistent and more species must be examined before a rational distribution pattern becomes apparent. © 1969 American Oil Chemists' Society.
