微波消解/ICP-MS法测定不同地点三种马先蒿16种元素

Determining of the Content of Determination of Elements of Pedicularis from Different Places by ICP-MS after Micriware-Assisted Digestion

利用微波消解/ICP-MS法对三种马先蒿中16种元素进行了含量测定,该方法的加样回收率在95%～102%之间,相对标准偏差在1.24%～2.18%之间,具有较高的准确度和精确度。结果表明不同种马先蒿各元素的含量均有所不同,而且不同种马先蒿中各元素与海拔有不同的线性关系。实验结果为马先蒿的药效性和药理、毒理提供理论依据。

The content of elements in Pedicularis was determined by ICP-MS aftermicriware-assisted digestion.Recovery and RSD of the method is 95%~102% and 1.24%~2.18% respectively,and the method is rapid and precise.There is different Element content in Pedicularis from different places.There are some relations between altitude and content in different places.The result of Pedicularis can provide theoretical basis for medicine research.
