摘要
A method for determination of fatty acids(FA) compositions in human serum by gas chromatography time-of flight mass spectrometry(GC-TOF MS) method was established.The FA in serum were directly transformed into the fatty acid methyl esters by 2.5% H2SO4-methanol.Heptadecanoic acid methyl esters were used as internal standard.The detection and separation of all the FA were performed within 33 min.The established method has the characteristic of simple operation,rapid analysis,high accuracy,large amount of information and safety.So it is suitable for the scientific research to the disease correlating FA.
