Direct gas chromatographic analysis of the unsaponifiable fraction of different oils with a polar capillary column

  • N. Frega

  • G. Lercker


The analysis of the unsaponifiable fraction of several oil samples was performed by a new gas chromatographic technique with a polar column of high thermal stability. This column was adequate for fractionating sterols, methyl sterols and alcohols of the unsaponifiable matter, and allowed the detection of peaks usually unresolved with nonpolar columns.
