摘要
目的测定与分析白术、白芍、玄参等8种药材中9种有机氯农药残留量。方法以混合溶剂超声提取样品、浓硫酸磺化净化,采用毛细管气相色谱,用HP-5弹性石英毛细管柱程序升温分离,微电子捕获检测器检测,峰面积外标法定量。结果延胡索、麦冬和杭白菊均检出滴滴涕,含量分别为0.439、45.017、5.434 ng.g-1;杭白菊检出五氯硝基苯,含量为1.030 ng.g-1;其余药材均未检出有机氯农药残留。结论浙八味药材大部分未检出有机氯农药残留或含量较低,均在规定的安全范围内。
OBJECTIVE To determine the content of nine kinds of organochlorine pesticides in ＂Zhejiang 8 famous kinds herbal medicine＂. METHODS The samples were extracted by uhrasonieation with mixed solvent and purified with sulfuric acid. Separtion was accomplished by GC with heated HP - 5 fused - silica capillary column with micro - electron capture detector. The external stand- ard was used. RESULTS Dichlorodiphenyl trichloroethane （DDT） was detected in Corydalis yanhusuo W. T. Wang, Ophiopogon japonicus （Thunb.）Ker- Gawl. and Chrysanthemum morifolium Ramat. The content of DDT were 0. 439,45. 017 and 5. 434 ng.g-1 respeccively. Pentachloronitrobenzene（PCNB） was detected in Chrysan- themum morifolium Ramat. The content was 1. 030 ng＇g These nine organochlorine pesticides were not detected in other samples. CONCLCUSION The content of bexachloro - cyclohexane （BHC） ,DDT and PCNB in most medicinal materials of ＂Zhejiang 8 famous kinds herbal medicine＂ were not detected.
