✦ Synopsis
The lipid composition of chokeberry, black currant and rose hip seeds was investigated. The seeds contain 19.3 g kg À1 , 22.0 g kg À1 and 8.2 g kg À1 glyceride oil respectively. The content of phospholipids, mainly phosphatidylcholine, phosphatidylinositol and phosphatidylethanolamine, was 2.8 g kg À1 , 1.3 g kg À1 and 1.4 g kg À1 , respectively. The total amounts of sterols were 1.2 g kg À1 , 1.4 g kg À1 and 0.4 g kg À1 . The main component was b-sitosterol, followed by campesterol and D 5 -avenasterol. In the tocopherol fraction (55.5 mg kg À1 in chokeberry oil, 249.6 mg kg À1 in black currant oil and 89.4 mg kg À1 in rose hip oil), a-tocopherol predominated in chokeberry oil (70.6 mg kg À1 ). g-Tocopherol was the main component in black currant oil (55.4 mg kg À1 ) and rose hip oil (71.0 mg kg À1 ). 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.
