Abstract
MAREKOV, I., B. DAMYANOVA, S. MOMCHILOVA, M. ZLATANOV, G. ANTOVA, M. ANGELOVAROMOVA and T. NENKOVA, 2009. Sterol composition of rapeseed varieties introduced in Bulgaria. Bulg. J. Agric. Sci., 15: 119-122 The composition of glyceride oils isolated from the seeds of 6 rapeseed varieties introduced in Bulgaria was investigated focusing on the biologically active substances: sterols and sterol esters. Sterols in the glyceride oils were found to be totally 3 g.kg-1 including 2 g.kg-1 free sterols and 1 g.kg-1 esterified sterols. β-Sitosterol predominated in both free and esterified sterols, being respectively 658–790 g.kg-1 and 471–700 g.kg-1, followed by campesterol and stigmasterol. Oleic acid (609–768 g.kg-1) was the main component among the fatty acids of the sterol esters, followed by palmitic acid (72–144 g.kg-1).
