摘要用加速溶剂萃取法（ASE）结合气质联用（GC—MS）分析检测葡萄酒中的甲霜灵残留，结果表明以正己烷：丙酮（1：1／V：V）为萃取溶剂，萃取温度50℃，萃取时间10min，萃取效果达到最佳水平。方法的平均添加回收率90．5％-101．2％，相对标准偏差1．46％-3．28％，检出限为0．01μg／mL。 This research is about the determination of metalaxyl in wine by ASE-GC-MS. From the result, we can see the parameters of extraction of metalaxyl in wines were n-hexane/acetone （1：1）, extraction temperature 50℃, extraction time 10min were optimized by use of ASE-GC-MS. The recoveries are between 90.5%-101.2%, RSD 1.46%-3.28%, the limit of determination were 0.01μg/mL.
