摘　　要：建立了微波辅助萃取-气相色谱法测定白菜中有机磷农药的分析方法,并与捣碎提取法进行比较,结果表明,微波辅助提取法优于捣碎提取法,且操作简便、省时省溶剂、对环境无污染。方法回收率在98.9%-106.7%,RSD为3.0%-5.9%,检出限为0.015 mg/kg,能满足当前蔬菜、水果中有机磷残留的检测要求。The analytic method of determination of organophosphoms pesticide residues in cabbage with microwave-assisted extraction （MAE） and gas chromatographic （GC） was set up. The result showed that MAE-GC excelled Cob extraction and the operation was simple. It was auto, no pollution and economical. The recovery rate ranged from 98.9% to 106.7%. The RSD was 3.0% - 5.9%. And the detecting limit was 0.015 mg/kg.It could meet the determination demand of organophosphorus pesticides in vegetables and fruits.
