中藥材有機氯劑農藥限量標準係中藥品質管制重要規範之ㄧ，本計畫以氣相層析儀/電子捕獲偵測器法（GC/ECD）進行生地黃、紫蘇葉、女貞子、澤瀉、山茱萸、遠志、蒼朮、西洋參及細辛等9種中藥材中BHC、DDT、aldrin、dieldrin、endrin、PCNB、chlordane、hexachlorobenzene、heptachlor 等9種有機氯劑農藥殘留量調查。9種中藥材，每種各20件，共180件檢體。結果澤瀉及蒼朮均未檢出有機氯劑農藥殘留；20件西洋參檢體均檢出BHC類、PCNB類及hexachlorobenzene，其殘留量分別為0.01∼5.26 ppm、0.36∼13.08 ppm及0.02∼0.50 ppm，另DDT類殘留量為N.D.∼0.30 ppm。其餘8種中藥材，除細辛1件檢出0.35
ppm PCNB外，其餘有機氯劑農藥殘留量均小於0.10 ppm。本計畫結果提供行政管理單位作為制定管制標準之參考依據。

The evaluation of organochlorine pesticide residues in raw materials of traditional Chinese medicine (TCM)is essential to the quality control of TCM. In this study, the contents of organochlorine pesticides in 9 raw
materials of TCM, including Rehmanniae Radix, Perillae Folium, Ligustri Lucidi Fructus, Alismatis Rhizoma,Corni Fructus, Polygalae Radix, Atractylodis Rhizoma, Panacis Quinquefolii Radix, and Asari Radix, were
investigated. For each raw material of TCM, 9 organochlorine pesticides, including BHC, DDT, aldrin, dieldrin,endrin, PCNB, hexachlorobenzene, chlordane, and heptachlor, were analyzed by GC/ECD and confirmed by
GC/MS/MS. Twenty samples per each raw material of TCM were tested. The results showed that the pesticide residues were not detected both in all samples of Alismatis Rhizoma and Atractylodis Rhizoma. However,BHCs, PCNB, and hexachlorobenzene existed in all samples of Panacis Quinquefolii Radix, in 0.01∼5.26 ppm,0.36∼13.08 ppm, and 0.02∼0.50 ppm, respectively. The residues of organochlorine pesticides in sample of
all species other than Panacis Quinquefolii Radix were less than 0.1 ppm, except one sample of Asari Radix,in which the residue of PCNB was 0.35 ppm. The results of this study could be uesd as the references for the
regulatory authority.
