| Abstract: |
| [Objective] To study the composition of phospholipids and fatty acids in different animals to exploit and utilize efficiently the resource of phospholipids and fatty acids from animals. [Methods] The composition of phospholipids and fatty acids in livers from four different animals was compared by the methods of organic solvents extracting, high performance thin layer chromatography (HPTLC) and high performance gas chromatography (HPGC). [Result] The livers from four different animals are rich in phosphatidylcholine (PC), phosphatidylethnolamine (PE) and unsaturated fatty acid. The percentages of C18∶2 and C20∶4, which are the important nutritional essential fatty acids, and 24.08% and 2.34% in rabbit liver. The percentage is the highest in the 4 animal livers. [Conclusion] The livers from different animals can be good resources for lipids and unsaturated fatty acids. |
