Abstract

The lipid composition of chokeberry, black currant and rose hip seeds was investigated. The seeds contain 19.3 g kgÿ1 , 22.0 g kgÿ1 and 8.2 g kgÿ1 glyceride oil respectively. The content of phospholipids, mainly phosphatidylcholine, phosphatidylinositol and phosphatidylethanolamine, was 2.8g kgÿ1 , 1.3g kgÿ1 and 1.4 g kgÿ1 , respectively. The total amounts of sterols were 1.2g kgÿ1 , 1.4 g kgÿ1 and 0.4 g kgÿ1 . The main component was b-sitosterol, followed by campesterol and D5 -avenasterol. In the tocopherol fraction (55.5mgkgÿ1 in chokeberry oil, 249.6mg kgÿ1 in black currant oil and 89.4mg kgÿ1 in rose hip oil), a-tocopherol predominated in chokeberry oil (70.6mg kgÿ1 ). g-Tocopherol was the main component in black currant oil (55.4mg kgÿ1 ) and rose hip oil (71.0mgkgÿ1 ). The fatty acid composition of triacylglycerols, individual phospholipids and sterol esters was also identi®ed. In the phospholipids and sterol esters, the more saturated fatty acids, mainly palmitic, stearic, and long chain fatty acids predominated.
