fatty acid composition, tocopherol and sterol contents in linseed (linum usitatissimum l.) varieties

The oil contents of linseeds were determined between 39.9% (antares) and 43.3% (railinus). the oleic acid contents of seed oils varied between 0.8% (maroc) and 24.8 (railinus). the linoleic acid contents of linseed oil change between 10.2% (avangard) and 48.2% (maroc), while the palmitic acid of oils ranged from 4.8% (antares) to 6.1% (maroc), stearic acid contents ranged between 4.7% (avangard) to 23.5% (maroc). also, linolenic acid contents of avangard oil was higher (59.9%) than those of results of other linseed oils. the p8 contents of linseed oil change between 1.1 mg/kg (railinus) and 16.4 mg/kg (avangard). also, the δ-tocopherol content of railinus oil was also higher (262.7 mg/kg) than those of other linseed oils (0.3-0.4 mg/kg). the total tocopherol in railinus seed oil was higher (437.4 mg/100 g) (p<0.05) than that of maroc seed oil (30.3 mg/100 g).
