摘要：

Microcolumns packed with a silica-based cation exchanger were used to separate triacylglycerols in vegetable oils. A supercritical mobile phase consisting of carbon dioxide, acetonitrile and isopropanol was used. Argentation chromatography results in separation according to the number of double bonds; in this work, separation was also obtained according to chain length and the nature of the double bonds. Full separation of molecular species of triacylglycerols in the investigated oils could be obtained after fractionation in reversed-phase liquid chromatography.
