摘　　要：采用气相色谱/串联三重四级杆质谱法(GC/MS/MS)建立了分析葱、蒜、洋葱及其制品中25种有机磷的分析方法。葱、蒜、洋葱及其制品经提取、净化处理后,采用气相色谱/串联三重四级杆质谱法检测,25种有机磷农药在线性范围内均呈现良好的线性关系,线性系数>0.99。该方法的检出限(LOD)为0.001~0.005 mg/kg。三水平六平行的实验结果表明,该类化合物的回收率为63%~115%,相对标准偏差(RSD)为0.67%~13.5%。方法重现性好、精密度高、操作简单,适用于对葱、蒜、洋葱及其制品中多种有机磷的检测。A method was developed for the determination of 25 organophosphorus pesticides in scallions,garlic,onion and its products by gas chromatography/triple quadrupole mass spectrometry（GC/MS/MS）.The scallions,garlic,onion and its products were extracted and purified,and then tested by gas chromatography/triple quadrupole mass spectrometry（GC/MS/MS）,the calibration curves of 25 organophosphorus pesticides with good linearity（coefficients of determination,R^2〉0. 99）. The limit of detection（LOD） of 0. 001~0. 005 mg/kg,and the recoveries of 25 organophosphorus compounds at the three spiked levels of six parallel were in the range of 63% ~ 115%,with relative standard deviations（RSD） were between 0. 67% ~ 13. 5%.The method with good reproducibility,high precision,simple operation. Therefore,it is suitable for analysis of organophosphorus pesticides in scallions,garlic,onions,and its products.
