DETERMINATION OF MOLECULAR-SPECIES OF TRIACYLGLYCEROLS FROM HIGHLY UNSATURATED PLANT OILS BY SUCCESSIVE APPLICATION OF SILVER ION AND REVERSED-PHASE TLC

A method for the quantitative determination of molecular species of tr iacylglycerols in highly unsaturated plant oils by consecutive use of different TLC techniques is described. Silver ion TLC in both analytic al and preparative mode has been followed by reversed phase TLC to giv e results compatible with those obtained with RP-HPLC and capillary GL C. The method has been applied to corn and cotton seed oils. The numbe r of the separated and quantified triacylglycerol species in these oil s prevails those reported in the literature.
