| The nutritional components of muscle in Cyprinus acutidorsalis Wang were analyzed using ordinary standard methods. The results showed that contents of moistur , crude protein, crude fat, crude ash were 79.29(±1.54)%,16.77(±0.31)%, 2.48(±0.11)% and 1.54(±0.11)% in fresh muscle, respectively. The fatty acid composition of muscle in C.acutidorsalis Wang were analyzed through gravimetric method and tested by gas chromatogrphy-mass spectrometry(GC-MS) technology. The results showed that, 18 kinds of fatty acids were separated and determined. Among them, there were 8 kinds of saturated fatty acids (SAF) including cyclopropaneoctanoic acid, 2-hexyl, dodecanoic acid, tetradecanoic acid-12-methyl, etradecanoic acid, pentadecanoic acid, hexadecanoic acid, heptadecanoic acid and octadecanoic acid; there were 4 kinds of monounsaturated fatty acid (MUFA) including 9-hexadecenoic acid, 9-octadecenoic acid, 11-octadecenoic acid, 11-eicosenoic acid, accounting for 40.4% of the total fatty acids; there were 6 kinds of polyunsaturated fatty acids (PUFA) including 9,12-octadecadienoic acid, 11,14-eicosadienoic acid, 9,12,15-octadecatrienoic acid, 11,14,17 eicosatrienoate,eicosatetraenoic acid and docosahexaenoic acid, accounting for 17.0% of the total fatty acids. |
