Abstract
As a result of the characterization of the fatty acid composition of the cultured sea cucumber, 54 kinds of fatty acids were identified in the Apostichopus japonicus body wall and internal organs. Major fatty acids are 16:1n-9, 23:1n-9, 20: 4n-6 and 20:5n-3. The n-9MUFA and n-3HUFA were relatively rich in sea cucumber. Therefore A.japonicus could be chosen as a promising source of n-9MUFA and n-3HUFA. Peaks 11, 19, 26, 33 and 38 are DMA 16: 0, DMA 17: 0, DMA 18: 0, DMA 19: 0 and DMA 20: 0 respectively were determined by GC-MS analysis. And they can be presumed to contain plasmalogens rich in sea cucumbers.As a result of analysis of lipid classes and their fatty acid composition of total lipids extracted from the sea cucumber, the content of BCFA in TAG was 7.18%. The ratio of n-9MUFA in 1-MG was the highest at 50.79%. DMA has a large number of DMAs distributed in PE, and the ratio of DMA 16: 0 is 21.96%. The content of n-3HUFA in PC was 28.58%.Wild sea cucumbers were rich in palmitoleic (C16:1n-7) and eicosapentaenoic acid (C20:5n-3), whereas cultured specimens were rich in eicosenoic (C20:1n-9) and arachidonic acid (C20:4n-6). In both types of sea cucumbers, the highest percentage of polyunsaturated fatty acids (PUFA) consisted of polar lipids (PL), followed by total lipids (TL) and neutral lipids (NL). Cultured sea cucumbers contained a higher percentage of total lipids (TL) than wild sea cucumbers did, whereas there was no significant difference between the two groups in the percentages of neutral (NL) and polar lipids (PL).
