花蕊石中9种无机元素初级形态研究

Study on Primary Speciation of Mineral Elements in Ophicalcitum

目的:测定中药花蕊石及水煎液中无机元素含量,对花蕊石无机元素的初级形态进行分析。方法:采用微波消解-电感耦合等离子体质谱法(ICP-MS)测定花蕊石中9种无机元素的含量,并进行了初级形态分析。结果:各元素在残渣中的含量均远远超过其在溶液中的含量。元素在原药中含量特征如下Mg>Ca>Fe>K>Zn>Mn>Cu,其中Se,Cu,Mo,K的提取率较高。结论:矿物药元素水煎液提取率和浸留比与植物药相比相对较小,花蕊石中Se,Cu可以认为是该药中作用最大的元素或最特征的元素。

Objective：To determine the trace elements in traditional Chinese Medicine of ophicslcite and its decoction,and the primary speciation analysis on the trace elements of Ophicalcitum.Method：ICP-MS was used to determine the content of 13 trace elements and their primary speciation also been studied.Result：The content of elements in the residue was far more than the content in the solution.The content of elements in original drug was as follows：Mg Ca Fe K Zn Mn Cu,among which Se,Cu,Mo,K were in a higher extraction rate.Conclu-sion：The mineral medicine decoction extraction rate and the leaching residue ratio were relatively smaller than bo-tanical drug.In ophicslcite,Se,Cu could be considered to be the two largest elements of the role of the drug or the most characteristic elements.
