Lipids from Cysts of Aral Sea Brine Shrimp Artemia parthenogenetica

摘要

The contents and compositions of free (FL) and bound lipids (BL) from cysts of Aral Sea brine shrimp Artemia parthenogenetica were established. The yields of FL and BL were 12.3 and 2.23 mass% of the cysts. The BL group composition included neutral lipids (0.65%), glycolipids (GL) (0.34%), and phospholipids (PL) (1.24%). The lipophilic components of FL were identified as sterols, hydrocarbons including squalene, triterpenols, and xanthophylls. Fatty acids (FAs) of lipids included 16-17 components. FL were dominated by FAs 18:1, 16:1, and 16:0; GL, 16:0 and total 18:1 and 18:3; PL, total 18:1 and 18:3. Polyunsaturated FAs (20:4, 20:5, and 22:6) were not detected in lipids from the studied sample of A. parthenogenetica cysts.
