中藥材中有機氯劑農藥殘留檢驗(Ⅰ)

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

摘要


中藥材重金屬之限量標準係中藥材品質管制之重要規範之一,故本計畫利用氣相層析儀/電子捕捉偵測器法(GC-ECD)針對主要價購於藥廠之桂皮、桂枝、生杜仲、枇杷葉、白及、晉耆、茯苓、甘草、白芍、大黃、麻黃、桔梗、黃連、當歸、番瀉葉、乾薑、山藥、百合、紅參、川芎等20種中藥材,進行α-BHC(α-蟲必死)、β-BHC(β-蟲必死)、γ-BHC(靈丹)、δ-BHC(δ-蟲必死)、o,p'-DDE(2,4'-滴滴易)、p,p'-DDE(4,4'-滴滴易)、o,p'-DDT(2,4'-化滴滴涕)、p,p'-DDT(4,4'-滴滴涕)、Aldrin(阿特靈)、Dieldrin(地特靈)、Endrin(安特靈)、PCNB(五氯硝苯)、Chlordane(可氯丹)、Hexachlorobenzene(六氯苯)、Heptachlor(飛佈達)等15種有機氯劑農藥之背景值調查。結果17種中藥材未檢出α-BHC等15種有機氯劑農藥,另桔梗、枇杷葉及紅參3種藥材則檢出含有機氯劑農藥。其中紅參20件檢體均檢出一種以上之有機氯劑農藥,其BHC總量、PCNB、Hexachlorobenzene之平均檢出量分別為1.90、1.00、0.14ppm。桔梗1件檢出p,p'-DDE,其含量為0.22ppm。枇杷葉3件檢出o,p'-DDT,平均含量為0.06ppm。本結果將可提供行政管理單位作為限量標準制定評估之參考依據。

The limitation of organochlorine pesticide in raw materials of traditional Chinese medicine (TCM) is one of important regulation issues for the implementation of GMP in Chinese pharmaceuticals. Mostly purchased from Chinese pharmaceuticals, twenty raw materials of TCM including Cinnamomi Cortex, Cinnamomi Ramulus, Eucommiae Cortex, Eriobotryae Folium, Bletillae Rhizoma, Astragali Radix, Poria, Glycyrrhizae Radix, Paeoniae Alba Radix, Rhei Radix et Rhizoma, Ephedrae Herba, Platycodi Radix, Coptidis Rhizoma, Angelicae Sinensis Radix, Sennae Folium, Zingieris Rhizoma, Dioscoreae Rhizoma, Lilii Bulbus, Ginseng Rubra Radix et Rhizom, and Chuanxiong Rhizoma were monitored for the survey. The amounts of the residues of 15 organochlorine pesticides including α-BHC, β-BHC, γ-BHC, δ-BHC, o,p'-DDE, p,p'-DDE, o,p'-DDT, p,p'-DDT, Aldrin, Dieldrin, Endrin, PCNB, Chlordane, Hexachlorobenzene, and Heptachlor in the TCM were determined by GC/ECD and conformed by GC/MS method. The pesticide residues in seventeen selected TCM were not detected. Three kinds of organochlorine pesticides, BHCs, PCNB, and Hexachlorobenzene were found in all Red Ginseng samples, with average amounts of 1.90 ppm, 1.00 ppm, and 0.14 ppm, respectively. Three samples of Loquat Leaf and one sample of Platygala Root were detected to contain an average of 0.06 ppm o,p'-DDT and 0.22 ppm p,p'-DDE, respectively. These results could provide limitation assessment of organochlorine pesticide residues in raw materials of TCM for the regulatory authority.
