Studies on the constituents of sterols, 4α-methylsterols, and triterpene alcohols in a number of vegetable oils have led to the identification and characterization of one twenty-eight compounds in all (fifty-six of sterols, thirty-one of 4α-methylsterols, and forty-one of triterpene alcohols) which included a number of compounds detected for the first time in higher plants, in addition to twenty-eight new or newly found natural products. The occurrence and distribution of these compounds in vegetable oils were extensively investigated. In addition to these, the characterization of sterols and triterpene alcohols has been studied with the aid of gas chromatography, especially on glass capillary columns, and nuclear magnetic resonance (NMR) spectroscopy. The determination of the stereochemistry at C-24 of a large number of 24-alkylated sterols, 4α-methylsterols, and tetracyclic triterpene alcohols was performed with high-resolution <SUP>1</SUP>H-NMR and <SUP>13</SUP>C-NMR spectroscopy.
