| Abstract: | Lipids from five cultivars of highbush blueberries (Vaccinium corymbosum L.) were extracted and fractionated into neutral lipids (60–66%), glycolipids (20–22%) and phospholipids (14–18%). The major
fatty acids in all fractions were palmitic (16∶0), oleic (18∶1), linoleic (18∶2), and linolenic (18∶3) acids. All lipid classes
had a large concentration of C18 polyunsaturated acids (84–92%), indicating that blueberries are a rich source of linoleic and linolenic acids. Changes in
the fatty acid composition of neutral lipids and phospholipids were not significantly different among the five cultivars,
but significant differences were noted in the ratios of linoleic and linolenic acids in the glycolipids fraction. |
