STUDIES ON STEROL MIXTURES .5. STEROLS IN SUNFLOWER OIL AND OTHER PLANT OILS

Abstract

Sterol mixtures from 21 different plant oils were studied by gas chromatography. Comparison with sterol fractions from seed oils of pure breeding varieties of Helianthus anuus revealed that the quantitative composition is little affected by variety. Furthermore, the variations in fat content, unsaponifiable lipids and in the content and composition of sterol fractions during ripening of the seed were followed. A sterol, which has so far not been reported in sunflower oils, was found and identified as 24-methylene cholesterol.
