中文摘要：

目的：建立检测果实类中药材中41种有机磷农药残留的气相色谱分析方法。方法：样品以乙腈为提取剂超声提取,提取液经PSA固相萃取柱净化,正己烷∶丙酮（1∶1）洗脱,采用ZB1701毛细管色谱柱分离,GC-FPD检测器进行检测。结果：41种有机磷农药在50-500μg/kg范围内线性关系良好,相关系数（r）为0.9914-0.9987之间。分别对5种果实类中药材进行50、100、500μg/kg 3个浓度水平的添加回收率试验,平均回收率大部分在70%-120%之间,相对标准偏差（RSD）小于15%。方法的定量限大多低于50μg/kg,符合农药残留痕量测定要求。结论：本方法准确度高,灵敏度好,操作简便。

英文摘要：

Objective： To establish the gas chromatographic method for the determination of 41 organophosphorus pesticides in fruit Chinese medicines. Methods： The sample were extracted with acetonitril, cleaned up by PSA solid phase extraction column, eluted by n-hexane∶acetme（1∶1）, and finally determinated by gas chromatographic-flame photometric detection（GC-FPD） in ZB1701 capillary column. Results： The standard calibration curves for 41 organophosphorus pesticides showed high correlation coefficient（r=0.9914-0.9987） over 50-500μg/kg. The average recoveries at the three fortification levels（50, 100, 500μg/kg） were between 70% and 120% with the relative standard deviation（RSD） under 15%. The limits of quantification（LOQ） were less than 50μg/kg. Conclusion： It is indicated that the method develop in this study is easier, more sensitive and has a better purification effect.
