摘　　要：分别采集栽培、移栽及野生山莨菪样品,采用原子吸收光谱仪测定元素钾、钠、钙、镁、铁;用721分光光度计测定磷。结果表明:栽培、移栽和野生山莨菪根部对各种矿物质元素积累能力类似,即:对镁和钠的积累最高,对磷最低。同时,钙的积累与其他几种元素呈负相关。野生山莨菪的多数元素含量均高于另外两种。The Anisodus tanguticus （Maxim.） Pascher is a Chinese traditional medicinal material and Tibet herb of local Qinghai.The authors collected,tanguticus and wild Anisodus tanguticus （Maxim.） Pascher,and analyzed the contents of mineral elements such as K,Ca,Fe,Na and Mg by atomic Absorption spetrometer,and P by 721 spectrophotometer.The results show that：samples in different places are all rich in Mg and Na while poor in P.At the same time,Ca has a negative correlation with other elements.Compared to the others,the amount of 4 elements is higher in wild Anisodus tanguticus is higher.
