| 摘 要： | 建立了西洋参中有机氯农药残留量的气相色谱的分析方法。样品以丙酮提取，在NaCl存在下，以二氯甲烷进行液液分配，提取液以浓H2SO4净化，采用SE－54弹性石英毛细管柱，GCECD检测有机氯（六六六，DDT异构体及七氯，艾氏剂）农药的残留量，最低检测浓度为3．2×10－2ng／g～1．4ng／g，添加回收率在80％～133．18％，并对北京及东北产西洋参药材进行了实际残留量测定。

| Abstract: | A GC-ECD method for determination of the residual organochlorine pesticides in Panax quinquefoliunz was described using SE-54 column. The residues were extracted from sample with acetone by saturating the extraction solvent with NaCI and simultaneously liquid-liquid partitioning by dichlormethane. The extracts were cleaned up by concentrated HZSO,. The detection limits were 0.032 ng/g-1. 4 ng/g. Recoveries of organochlorine pesticides were 80%-133.18% |
