A method is described for the enrichment of very long chain unsaturated fatty acids from total fatty acids of Ximenia oil and their identification as picolinyl esters by means of liquid chromatography-mass spectrometry with atmospheric pressure chemical ionization (LC-MS/APCI). The method is based on the use of preparative reversed phase HPLC and their subsequent identification by microbore LC-MS/APCI
描述了一种从西梅尼亚油总脂肪酸中富集极长链不饱和脂肪酸的方法,并通过液相色谱-质谱联用常压化学电离 (LC-MS/APCI) 将其鉴定为吡啶甲基酯。该方法基于使用制备型反相 HPLC 及其随后通过微孔 LC-MS/APCI 进行的鉴定。这两种技术的组合被用来识别不寻常的不饱和 VLCFAs,最高可达 tetracontenoic 酸。还合成了四十三碳烯酸的所有四种位置异构体以明确确认它们的结构。
