摘要:

目的 建立检测血液、尿液中2,4-D丁酯的高效液相色谱分析方法。方法 采用正己烷为样品萃取溶剂,色谱柱为Zorbax SB - Aq柱,流动相为V(甲醇) ∶ V(水) = 60 ∶ 40。结果 2,4-D丁酯在血液和尿液中的线性范围分别为0.10~10.00 μg/mL ( r≥0. 999 8)和0.08~8.00 μg/mL ( r≥0.999 5),检测限分别为0.002 0 μg/mL和0.001 8 μg/mL,准确度为94.5% ~104.5%,日内、日间精密度≤4.5% 。结论 本研究建立的血液、尿液中2,4-D丁酯的提取和HPLC检测方法,可应用于2,4-D丁酯中毒的快速检验和中毒死亡的法医学鉴定。

Abstract:

Objective To establish a HPLC method for determination of 2,4-D butyl ester in blood and urine. Methods Compound was extracted from blood and urine using ethyl acetate. Separation was achieved on Zorbax SB-Aq column using methanol-water(60 ∶ 40) as mobile phase. Results The calibration curve of 2,4-D butyl ester ranged from 0.10 μg/mL to 10.00 μg/mL in blood ( r ≥0. 999 8) and 0.08 μg/mL to 8.00 μg/mL in urine (r≥0.999 5), respectively. The limits of detection for the analyte was 0.002 0 μg/mL and 0.001 8 μg/mL in blood and urine, respectively. The intra and inter day assay precision were no more than 4.5%. The mean recovery ranged from 94.5% to 104.5%. Conclusions The pre-treatment and HPLC analysis of 2,4-D butyl ester in blood and urine can be used for rapid diagnosis of 2,4-D butyl ester poisoning and forensic identification of 2,4-D butyl ester poisoning death.
