摘　　要：应用ICP-AES技术,测定了不同产地柴胡矿质元素含量。(1)柴胡中五种常量矿质元素中K含量和累积量最高,五种微量矿质元素中Fe含量和累积量最高。(2)北京上庄柴胡中Ca,Mg,P,Na,Cu含量高,分别可达6.40,3.84,3.45,4.97mg.g-1和25.20μg.g-1,而山西万荣柴胡K,Ca,Mg,P,Zn,Mn,B含量低,分别仅为12.43,4.57,1.92,1.79mg.g-1和50.04,32.21,12.95μg.g-1。(3)不同产地柴胡间P∶K,Zn∶Fe,Cu∶Mn差异大,Mg∶Ca差异小。不同产地间柴胡矿质元素含量、累积量和比例存在较大差异。ICP-AES technique was used to determine the mineral elements in Bupleurum at different habitat.The results show that：（1） In Bupleurum,the content and accumulation of K was the highest among 5 macroelements,the content and accumulation of Fe was the highest among 5 microelements.（2） In Bupleurum,the content of Ca,Mg,P,Na and Cu was high in habitat of Beijing,the content can respectively reach to 6.40,3.84,3.45,4.97 mg·g-1,and 25.20 μg·g-1;while the content of K,Ca,Mg,P,Zn,Mn and Cu was low in habitat of Wanrong,and the content was only 12.43,4.57,1.92,1.79 mg·g-1 and 50.04,32.21,15.43 μg·g-1 respectively.（3） In Bupleurum,the content of P∶K,Zn∶Fe,Cu and Mn was significantly different at different habitat,while Mg and Ca showed little difference.Conclusion： In Bupleurum,the content,accumulation and proportion of mineral elements were differenct at different habitat.
