摘要：

目的:采用GC-MS法测定市售藻油中主要成分DHA、DPA及其他微量成分的含量。结果:3种市售藻油的甲酯化产物中,主要成分二十二碳六烯酸(DHA)甲酯含量为24.77~41.20%、二十二碳五烯酸(DPA)甲酯含量为4.00%~5.60%;此外,藻油的甲酯化产物中还含有19种饱和脂肪酸酯、24种不饱和脂肪酸酯,除了脂肪酸外,藻油中还含有少量的烃类、醇类和酮类物质。结论:市售复合型藻油为藻油与亚麻籽油等植物油按一定比例调和而成,且其DHA含量不满足国家标准GB 26400—2011的要求;角鲨烯和亚麻醇这两种微量成分的存在,使藻油比其他市售植物油更具保鲜和保健功能。

摘要：

Objective The content of the main components that DHA and DPA and other trace components of the algal oil on sale were detected by using the method of GC-MS. Result In the three kinds of the methyl esters of the algal oil on sale,the content of the docosahexaenoic acid methyl ester( DHA-ME) was 24. 77% ~ 41. 20%,docosapentenoic acid methyl ester( DPA-ME) was 4. 00% ~ 5. 60%.In addition,there were 19 kinds of saturated fatty acid ester and 24 kinds of unsaturated esters in the other methyl esters of the algal oil. In addition to the fatty acid,the algal oil also contained a small amount of hydrocarbons,alcohols and ketones. Conclusion Commercially available composite type of algal oil should be mixed according to certain proportion with algal oil and linseed oil and other vegetable oil,and the content of DHA did not meet requirements of the national standard GB 26400-2011. The existence of two kinds of trace components that squalene and linolenic alcohol,made that compared to other commercially available vegetable oil,algal oil was more fresh and had more health care function.
