三文鱼脂肪酸的气相色谱-质谱分析

Analysis of Fatty Acids in Salmon Oil with Gas Chromatography-Mass Spectrometry

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)。

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.
