摘要
利用高效液相色谱法测定葡萄酒中多菌灵残留量,样品以乙酸乙酯提取,二氯甲烷萃取净化,以ODS-C18柱(4.6mm×250mm,5μm)进行分析,流动相(V乙酸乙酯∶V乙酸铵=55∶45)流速为1mL/min时,多菌灵保留时间为7.016min,回收率为87.8%～107.5%,最低检出限为2×10-5mg/kg。
The residual carbendazim in grape wine was measured by HPLC and the process was as follows： samples extracted by ethyl acetate, then extractive purification of the solution by methylene chloride, then the solution analyzed by ODS-C18 column （4.6 min×250mm, 5μm）, mobile phase （V ethyl acetate：V ammonium acetate=55：45 ）, flow velocity as 1 mL/min, retention time of carbendazim as 7.016 min, recovery rate as 87.8 %～107.5 %, and the minimum detection limit as 2×10^-5 mg/kg.
