中藥材有機氯劑農藥殘留檢驗（V）

Survey on Organochlorine Pesticide Residues in Raw Materials of Traditional Chinese Medicine (V)

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一，本計畫以氣相層析儀／電子捕捉偵測器法(GC/ECD)進行枳殼、酸棗仁、木香、金銀花、白朮、薄荷、桑枝、羌活、吳茱萸、砂仁、川楝子、雞血藤、地龍、地榆、大腹皮、廣藿香、前胡、何首烏、龍膽及射干等20種中藥材之aldrin、BHC、chlordane、DDT、dicofol、dieldrin、endosulfan、endrin、fenvalerate、heptachlor、hexachlorobenzene及quintozene等12種有機氯劑農藥殘留量調查。結果顯示，20種中藥材，每種各20件，共400件檢體中，金銀花10件檢出DDT，其殘留量範圍為0.010~0.167 ppm；薄荷3件檢出fenvalerate，其殘留量範圍為0.101~0.340ppm；地榆1件檢出PCNB，其殘留量為0.006 ppm；其餘均未檢出有機氯劑農藥殘留。本計畫結果已提供行政管理單位，作為制定管制標準之參考依據。

The evaluation of organochlorine pesticides 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 20 raw materials of TCM, including Citri Immaturus Fructus, Ziziphi Spinosae Semen, Aucklandiae Radix, Lonicerae Flos, Atractylodis Macrocephalae Rhizoma, Menthae Herba, Mori Ramulus, Notopterygii Rhizoma et Radix, Evodiae Fructus, Amomi Fructus, Toosendan Fructus, Spatholobi Caulis, Pheretma, Sanguisorbae Radix, Arecae Pericarpium, Pogostemonis Herba, Peucedani Radix, Polygoni Multiflori Radix, Gentianae Rhizoma et Radix, and Belamcandae Rhizoma, were investigated. For each raw material of TCM, the residues of 12 organochlorine pesticides, such as aldrin, BHC, chlordane, DDT, dicofol, dieldrin, endosulfan, endrin, fenvalerate, heptachlor, hexachlorobenzene, and quintozene, were analyzed by GC/ECD and comfirmed by GC/MS. Twenty samples per each raw material of TCM were tested. The result showed that 10 samples of Lonicerae Flos were detected to contain DDT of concentration ranging 0.010~0.167 ppm, 3 samples of Menthae Herba contained fenvalerate of 0.101~0.340 ppm and one of Sanguisorbae Radix contained PCNB of 0.006 ppm. The results of this study could be uesd as the references for the regulatory authority.
