摘　　要：本文以马油为检材,进行甲酯化后利用气相色谱-质谱联用法(GC-MS)对其中的游离脂肪酸成分进行了定性定量分析。分析结果表明,马油中含有多种饱和脂肪酸、单不饱和脂肪酸和多不饱和脂肪酸,其中以棕榈酸、油酸和亚油酸的含量为最丰,油酸和亚油酸的相对含量之和超过50%。本文还利用微弱发光检测技术对马油中主成分油酸在体外淬灭单线态氧的能力进行了研究,结果显示油酸在一定浓度范围内具有较明显的抗氧化功能,马油中油酸的含量高达47.5mg/g,由此可见,马油在一定浓度范围内也会具有抗氧化能力。In this paper,the free fatty acids composition of horse oil was analyzed qualitatively and quantitatively by gas chromatography-mass spectrometry (GC-MS) after methylesterification treatment.The results showed that large amounts of saturated,monounsaturated and polyunsaturated fatty acids (PUFAs) were contained in the horse oil,among which,the contents of palmitic acid,oleic acid and linoleic acid are the most,the sum of relative contents of oleic acid and linoleic acid is more than 50%.Oleic acid’s ability...
