Abstract

The unsaponifiables from 19 vegetable oils were divided into 4-methylsterol fraction, triterpene alcohol fraction and two other fractions by thin layer chromatography. The 4-methylsterol and triterpene alcohol fractions were analyzed by gas liquid chromatography, and identification of major components was carried out by gas liquid chromatography and combined gas chromatography-mass spectrometry. Gramisterol(24-methylenelophenol), citrostadienol and obtusifoliol were present in all oils, and the presence of a 4-methylsterol, presumably cycloeucalenol, was indicated in most of the oils. Cycloartenol and 24-methylenecycloartanol were found as common triterpene alcohols in all oils, and the occurrence of cyclobranol(24-methylcycloartenol), cycloartanol, and α- and β-amyrins was demonstrated in most of the oils.
