采用振荡离心法提取、柱层析法净化技术,成功建立了气相色谱-质谱法同时测定银杏叶中五种有机磷农药残留量的方法.结果表明,采用程序升温,所测定的五种有机磷农药在HP-5MS柱上得到了很好的分离,且方法简单、快速、灵敏,完全符合实际需要.方法回收率在88.8%～102%之间,相对标准偏差为1.6%～4.7%,最低定量检出浓度在0.01～0.05 mg/kg之间.

A simple and rapid method based on gas chromatography-mass spectrometry (GC-MS) for simultaneous determination of pesticides' multiresidues in Ginkgo biloba leaves is developed.It shows that the organophosphorus pesticides are separated well on a HP-5MS column by the optimized temperature program.The recovery for fortified sample is between 88.8% and 102%,with the relative standard deviation (RSD) from 1.6% to 4.7%,and the concentration limit of detection is in the range of 0.01 -0.05 mg/kg.
