摘要:

本文用气相色谱,气相色谱-质谱分析了舟山渔场13种海鱼的脂肪酸,鉴定了鱼油脂中饱和及不饱和脂肪酸,对鱼油中的脂肪酸组成作了初步研究。分析结果表明,舟山渔场鱼类富含二十碳五烯酸和二十二碳六烯酸,具有开发利用价值。

STUDY ON COMPOSITIONS OF SATURATED AND UNSATURATED FATTY ACIDS IN FISH OILS FROM ZHOUSHAN FISHERY

Abstract:

The lipids extracted from 13 specieces of fish caught in Zhoushan fishery ground were saponified and esterified. Fatty acid methyl ester was analyzed by gas chromatography and gas chromatography-mass spetrometer. Saturated and unsaturated fatty acids were identified and the fatty acid compositions were studied. The results show that the studied fish species in Zhoushan fishery ground have high cis-5,8,11,14,17-eicosapentaenoic acid and eis-4,7,10,13,16,19-docsahexaenoic acid contents. The fish oils may have important untrituious values on the prevention and treatment of cardivascular and hypertension diseases.

Key words: Fish oils, Eicosapentaenoic acid (20:3 w3), Docsahexaenoic acid(22:6 w3), zhoushan fishery, Coronary heart disease
