Total lipids in medium and low erucic acid cul‐tivars of rapeseed (Brassica napus var. Sinus and Janpol, resp.) were fractionated into polar and non‐polar constituents. Triglycerides, diglycerides, mono‐glycerides, free fatty acids, sterol esters, sterols, phos‐pholipids and glycolipids were quantitated and their fatty acid compositions determined. Triglycerides and phospholipids constituted 92 and 3.4%, resp., of the total lipid from each cultivar. Triglycerides were lower in saturated fatty acids but higher in monoun‐saturated acids and linolenic acid than other lipid fractions. Phospholipids and glycolipids were higher in linoleic acid content than other lipid classes. Generally, the reduction in long chain, monoenoic, fatty acids was associated with a corresponding increase in oleic acid in most low erucic acid frac‐tions.
