  • 摘要: 本文报道了多菌灵在西洋参中残留量的HPLC检测方法.当添加水平在1.0一5.0μg·l-1时,根中回收率为60一76%:添加水平在0.5一2μg·l-1时,茎叶中回收率为70一80%;土壤添加2.5μg·l-1时,回收率为84%.茎叶、根、土壤中残留量测定的相对标准偏差分别为2.16%.6.17%.1.24%.检测极限均为0.1μg·l-1多菌灵在茎叶和土壤中的消解动态方程为C=118.42e-0.1156 和 C=18.84e-0.1912 半衰期为5.87d和3.63d.
    Abstract: A HPLC method for determination of the residues of Carbendazim in Panax quinque-folium was described using a reversed phade column,packed with ODS and UA detection at 277nm. The mobile phase was a mixture of methanol-water-tetrahydrofuran(49:49:2). Recoveries of Carbendazim were 70-80% for 0.5-2μg·g-1 ranges in the stem and leaves, 60-76% for 1.0-5.0μg·g-1 ranges in the root, and 84% for 2.5μg·g-1 in the soil. The relative standard deviation were 2.16%, 6.17% and 1.24%, respectively. The detection limit was 0.lμg·g-1 for all samples. The elimination equation of dynamic state and the half-life time of Carbendazim for the stem and leaves and the soil were C=118.42e-0.1156 and C=18.84e-0.1912, and 5.87 and 3.63 days, respectively.
