The changes of content and composition of flax seed fatty acids, sterols and tocopherols during vegetation in period April - July were investigated. The quantity of glyceride oil increased from 174 - 327g.kg-1 between 21 - 35 day after flowering. In the triacylglycerol fraction the content of oleic acid decreased from 383 g.kg-1 to 322 g.kg-1 at the expense increasing of linolenic acid from 294 to 342 g.kg-1. In sterol esters higher content of monounsaturated oleic acid was detected – from 392 g.kg-1 at 21 day after flowering to 517 g.kg-1 at 35 day after flowering. The quantity of stearic acid decreased from 167 g.kg-1 to 107 g.kg-1. The content of sterols was 4 g.kg-1 in whole period. в-Sitosterol was the main component in free 454 – 523 g.kg-1 and esterified sterols 553 – 566 g.kg-1 during vegetation, followed by campesterol. The percentage of tocopherols was highest in the first stage of development 975 mg/kg vs 898 mg/kg in the last period.
