摘　　要：采用ICP-AES/ICP-MS技术对7种土壤种植下的4种柴胡种质药材中21种常量及微量元素含量进行了分析测定。综合考虑种质和土壤对柴胡药材中常量和微量元素含量的影响,K,Ca,Mg,Na 4种常量元素含量受种质影响较大,Fe,Cu,Ni,Ti,Cr,V,Zr,Se,Sn,Cs,Cd,Hg,Pb等13种微量元素含量则受土壤影响较大;4种柴胡种质中,以甘肃种质的柴胡药材中常量和微量元素含量较高,中柴1号柴胡药材中常量和微量元素含量较低;在7种土壤种植下,以在北京市延庆县永宁镇盛世营村山地土壤上种植的柴胡药材中常量及微量元素含量较低,而在北京市怀柔区喇嘛沟门乡东岔村土壤上种植的柴胡药材中常量及微量元素含量较高。这些研究结果为了解各自药材中药效成分的含量及其疗效差异起着重要作用,也为选择种质和土壤及栽培出高产优质的柴胡提供重要依据。Contents of 21 elements, including of K, Ca, Mg, Na, Fe, Mn, Cu, Zn, Ni, Ti, Cr, Mo, V, Zr, Co, Se, Sn, Cs, Cd, Hg, and Pb, in the roots of four germplasms Bupleurum L. planted in the soils from seven regions, were analyzed by ICPMS/ICP-AES. The results showed that the contents of K, Ca, Mg and Na are mainly ascribed to the effect of germplasms, and the contents of Fe, Cu, Ni, Ti, Cr, V, Zr, Se, Sn, Cs, Cd, Hg and Pb are mainly ascribed to the effect of soils considering the integrated effects of germplasms and soils. Generally, element contents in the root of G-GS were higher and that in the root of GZC were lower in the four germplasms of Bupleurum L. Element contents in the root of Bupleurum L. planted in S-HR were higher, while that planted in S-YQS were lower as a whole among these soils from seven regions. The difference in the element contents has an important effect on the research into the contents of officinal ingredients and their curative effect in the roots of four original Bupleurum L. germplasms planted in the soils from seven regions. And this study also provides an important scien- tific foundation for the choices of germplasms and soils in the cultivation of high-yield and high-quality Bupleurum L.
