| Abstract: |
| In order to realize the effective utilization of by-products sheep bones and provide basic data for the development of high-value sheep bone oil products, sheep leg bones were used as raw materials to extract oil, and the glyceride composition, lipidomics and fatty acid composition of sheep bone oil were analyzed by high performance liquid chromatography (HPLC), multidimensional mass spectrometry shotgun method (MDMS-SL) and gas chromatography-mass spectrometry (GC-MS) respectively. The results showed that the content of triglycerides in sheep bone oil reached 96.76%, and a small amount of diglycerides (1.41%) was identified, while no monoglycerides was detected. A total of 19 acylcarnitines, 17 sphingomyelins, 37 phosphatidylcholines and 39 triglycerides were identified in sheep bone oil, with total contents of 5.76, 96.58, 85.18 nmol/g and 15.76 μmol/g, respectively. 11 kinds of fatty acids including 11.51% saturated fatty acids, 72.34% monounsaturated fatty acids and 7.56% polyunsaturated fatty acids were detected in sheep bone oil. |
