摘要: 采用Bligh-Dyer提取法对三文鱼鱼肉中的脂肪酸进行提取,利用气相色谱-质谱联用仪进行分析测定,共检测出25中脂肪酸。不饱和脂肪酸为16种,相对百分含量占检出所有脂肪酸的71.90%。其中,二十碳五烯酸(EPA)为9.46%,二十二碳六烯酸(DHA)为11.77%,同时检出了15-二十四碳烯酸(NA)。

Abstract: Salmon oil was extracted via Bligh-Dyer method,and its fatty acid compositions were analyzed with gas chromatography-mass spectrometry(GC-MS). Results showed that 25 fatty acids are identified,inculding 16 unsaturated fatty acids,whose total relative content accounts for 71.90% of the total fatty acid content. The percentages of eicosapentaenoic acid(EPA) and docosahexaenoic acid(DHA) are 9.46% and 11.77% respectively,and 15-tetracosenoic acid(NA) exists in salmon oil.

Key words: salmon, fatty acid, gas chromatography-mass spectrometry
