### Abstract

Canola seeds were extracted with supercritical carbon dioxide at 313 K and 41.4 MPa, and the oil collected as fractions dependent on the volume of extractant used. The composition and oxidative stability of four isolated fractions were evaluated. As the volume of extractant increased, the amount of linolenic acid in the fractions decreased from 11.4 to 9.3%. The amounts of phospholipid increased from 0.35 to 9.95 mg/kg, respectively in fraction one and four, as the volume of carbon dioxide used for extraction increased. Tocopherols were extracted at a similar rate and equal amounts were present in all fractions. The amount of sterol was 51% higher in the last fraction compared to the first fraction. Fractions obtained at the end of extraction contained higher amounts of unsaponifiables and phospholipids, and showed better oxidative stability.
