人參類藥材中抗黴菌劑之調查(II)

SURVEY OF FUNGICIDE RESIDUES IN GINSENG (II)

人參因合糖量及合水量高，因此容易因環境因子之影響而導致黴菌之滋生，甚至產毒影響中藥材之安全性。為瞭解廣泛使用之粉光參藥材，在販售前是否噴灑，燻蒸或添加抗黴菌劑，以防止黴菌之滋長及破壞。以逢機取機方式，抽購60件粉光參，以HPLC之方法分析TBZ （Thiabendazole）, OPP （O-phenylphenol）, BP （Biphenyl） 及以 GC/ECD 之方法分析 CS 2 及 CCl 4，結果均未檢出。另 TBZ, OPP, BP 各添加20~80 µg之平均回收率分別為60.3%，78.8%，86.2%，最低檢出量分別為1 ppm, 0.75 ppm, 0.75 ppm, CS2, CCl4 之平均添加回收率分別為61.2%，82.5%，最低檢出量分別為0.5 ppm, 0.03 ppm， 在檢測範圍內具有良好的線性關係。藥材經 CS2 與 CCl4 燻蒸後，在其最低之檢測範圍，均可檢出其含量。

Multiresidue analysis methods using HPLC and GC/ECD were used to analyze the thiabendazole (TBZ), o-phenylpheonl (OPP), biphenyl (BP), CS2 and CC14 content in Panacis Quinquefolii Radix. The average recoveries of TBZ, OPP and BP were 60.3, 78 .8 and 86.2% at 20, 40 and 80 µg fortification levels, respectively and the detection limits were 1, 0.75 and 0.75 ppm. The average recoveries of CS2 and CC14 were 61.2 and 82.5% and the detection limits were 0.5, 0.03 ppm, respectively. Linear regression analysis gave good linear relationships. Sixty samples of Panacis Quinquefolii Radix were analyzed, but none of the samples were detectable.
