采用4，4-二甲基恶唑啉（DMOX）衍生化，气相色谱-质谱法测定多不饱和脂肪酸中双键的位置。 提出了一种从脂肪酸甲酯（FAME）出发制备DMOX的方法。 这些衍生物的最有趣的特性，特别是长链多烯脂肪酸的分析。 DMOX衍生物与FAME的组合使用对于鉴定未知样品中的脂肪酸非常有用。
The location of double bonds in polyunsaturated fatty acids is determined by gas chromatography-mass spectrometry after 4,4-dimethyloxazoline (DMOX) derivatization. A procedure for DMOX preparation, starting from fatty acid methyl esters (FAMEs) is proposed. The most interesting properties of these derivatives are presented especially for the analysis of long-chain polyenoic fatty acids. The use of DMOX derivatives in combination with FAMEs can be very useful for the identification of fatty acids in unknown samples.
