对市售深海鱼油胶囊中的脂肪酸化合物成分进行研究。通过甲酯化反应，以正己烷为溶剂直接进样，采用气相色谱—质谱联用技术对脂肪酸甲酯成分进行分离并辅助 NIST 检索工具分析成分。结果表明鱼油胶囊中主要含有棕榈酸、棕榈油酸、油酸、DHA、EPA 等21种脂肪酸。通过面积归一化法计算出各种脂肪酸相对含量，其中不饱和脂肪酸含量接近70％。该实验方法简便快捷，可为同类产品脂肪酸含量研究提供借鉴。
對市售深海魚油膠囊中的脂肪痠化閤物成分進行研究。通過甲酯化反應，以正己烷為溶劑直接進樣，採用氣相色譜—質譜聯用技術對脂肪痠甲酯成分進行分離併輔助 NIST 檢索工具分析成分。結果錶明魚油膠囊中主要含有棕櫚痠、棕櫚油痠、油痠、DHA、EPA 等21種脂肪痠。通過麵積歸一化法計算齣各種脂肪痠相對含量，其中不飽和脂肪痠含量接近70％。該實驗方法簡便快捷，可為同類產品脂肪痠含量研究提供藉鑒。

The fatty acid compound ingredients in fish oil capsule bought from market were studied. Through esterification reaction,using hexane as solvent with direct injection,the fatty acid methyl ester composition was separated by gas chromatography -mass spectrometry and analyzed the composition by NIST assisted search tool.The results showed that fish oil capsule was mainly composed of 21 kinds of fatty acids,including palmitic acid,palmitoleic acid,oleic acid,DHA,EPA.The relative contents of the fatty acids were calculated by area normalization method.The content of unsaturated fatty acid was close to 70%.The method is simple and fast,which can provide reference for the similar products.
