ICP-AES技术测定不同产地柴胡矿质元素

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。

Determination of mineral elements in Bupleurum based on ICP-AES

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 x g(-1), and 25.20 microg x 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 x g(-1) and 50.04, 32.21, 15.43 microg x g 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 difference at different habitat.
