Objective To establish a method for determining 2,4-D butylate in serum by gas chromatography (GC) and to provide a basis for the diagnosis and treatment of clinical poisoning.Methods Serum 2,4-D butylate level was determined by the following steps:mixing serum (0.5 ml) with trichloromethane (2.0 ml),adequately shaking for extraction,standing for 5 min,centrifuging at 4 000 rpm for 10 min,blowdrying the trichloromethane layer with nitrogen,adding ethanol (50 μl) to a certain volume,adding the sample (1.0 μl),and performing GC with a hydrogen flame ionization detector.Results Serum 2,4-D butylate level showed a linear relationship within 5~40 μg/ml,with a regression equation of y=1 831.6.4x-899.4 (r=0.999 2); the minimum detectable concentration was 1.0 μg/ml.The recovery rate was 88.7%~103.0% (relative standard deviation (RSD) 3.8%~5.0%).The intra-day RSD and inter-day RSD were 3.87-4.92% and 3.33%~5.34%,respectively.Conclusion This determination method is simple,efficient,and accurate and provides a good means for rapid diagnosis and treatment of 2,4-D butylate poisoning.
