建立了黄芪、甘草中有机氯农药残留量的气相色谱分析方法。样品以丙酮提取，在氯化钠存在下，以二氯甲烷进行液液分配，提取液以浓硫酸净化，采用ＳＥ－５４弹性石英毛细管柱，ＧＣ／ＥＣＤ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２×１０－２～１４ｎｇ／ｇ，加样回收率在７７８％～１０２５％，并对不同产地的药材进行了实际残留量测定 A gas chromatographic method for the determination of organochlorine pesticide residues in Radix Astragali and Radix Glycyrrhizae was established. Samples were extracted with acetone, and liquid-liquid was partitioned with dichloromethane in the presence of sodium chloride. The extract was purified by concentrated sulfuric acid. The organochlorines were detected by GC / ECD using SE-54 flexible quartz capillary column (BHC, DDT And the concentration of heptachlor and aldrin) pesticides. The minimum detectable concentration was 3 × 10-2 ~ 14ng / g and the recoveries were 778% -1025% The medicinal materials from different areas were measured the actual residue
