不同产地厚朴中重金属及有害元素检测

Determination of heavy metals and harmful elements of Houpo from different habitats

目的:检测不同产地厚朴中重金属及有害元素含量。方法:采用原子荧光光度法和原子吸收分光光度法对全国8省11个不同产地厚朴中铅、镉、砷、汞、铜进行测定。结果:不同产地厚朴中所含重金属及有害元素的量有一定差异,11个样品中除有4个样品的铅含量较高外,其余均符合"药用植物及制剂外经贸绿色行业标准"要求。结论:所建立的方法可行,其含量测定结果可为厚朴药材的规范化种植和质量评价提供参考。

Objective： To determine the contents of heavy metals and harmful elements of Houpo from different habitats. Method： The contents of Pb, Cd, As, Hg, Cu from 11 different habitats in 8 provinces were determined by atomic fl uorimetry and atomic absorption spectrophotometry. Result： There were difference existed in the contents of heavy metals and harmful elements of different samples. All results except Pb contents of 4 samples were in the range of ＂green trade standards of medicinal plants and preparation of foreign trade and economic cooperation＂ requirements. Conclusion： The established method is feasible and referable for GAP and quality evaluation of Houpo.
