臺灣地區市售中藥材及其製劑之重金屬含量調查

INVESTIGATION OF HEAVY METALS FROM BOTH CRUDE DRUGS AND THEIR PREPARATIONS IN TAIWAN MARKET

八寶粉類製劑其來源由藥廠者其含鉛量最高者為60.0ppm，由中藥房及中醫診所調製者其含鉛量在100ppm以上者有三件，其中一件含鉛量高達3637ppm；由此二種來源的檢體其含汞量平均小於1ppm。10種常用礦物性藥材，包括龍骨、石膏、赤石脂等和40件含有此類礦物性藥材成分之中藥製劑做鉛、銅、鎘、鈷、鎳、錳、汞及砷八種重金屬含量測定。經測試結果在礦物性藥材重金屬含量如下：鉛→以龍骨、赤石脂、牡較高。銅→以龍骨、赤石脂、自然銅較高。鎳→以赤石脂較高。站→以自然銅較高。錳→以龍骨、赤石脂、代赭石、牡蠣較高。另外在製劑部分濃縮製劑的重金屬含量較非濃縮製劑為低。 Various crude drugs and preparations were collected from the market and the content of heavy metals (Pb, Co, Cu, Ni, Mn, Cd, Hg and As) of these samples was determined by the atomic absorption spectrophotometry. Following results were found: those with high lead content: fossi bone, halloysite and oyster shell; with high copper content: fossil bone, halloysite and pyritum; with high nickel content: halloysite, with high cobalt content: pyritum; with high manganese: fossil bone, halloysite, hematitum and oyster shell. In the part of the preparations, the heavy metal content of the concentrated were found to be lower than the non-concentrated ones.
