摘要：
The composition of sterols and sterol esters and the fatty acid composition of sterol esters in the glyceride oil isolated from the seeds of nine Bulgarian sunflower varieties were examined. The total sterol content was estimated to be 3-4 g.kg(-1) with the amount of free sterols - 658-790 g.kg(-1) and that of sterol esters - 471-700 g.kg(-1). b-Sitosterol was the main component in both sterol fractions followed by stigmasterol and campesterol. Palmitic acid was the main fatty acid component (225-485 g.kg(-1)) in sterol ester fraction, followed by oleic (203-420 g.kg(-1)) and linoleic (81-176 g.kg(-1)) acid.
