摘要
目的对太子参水提液中3种金属元素Cu,Mn,Zn进行形态研究。方法采用电感耦合等离子体质谱(ICP-MS)测定太子参及太子参水提液中3种金属元素的含量,并用反相高效色谱(RP-HPLC)-电感耦合等离子体质谱(ICP-MS)联用技术对太子参水提液中的Cu,Mn,Zn元素进行形态分析。结果太子参水提液中金属元素Cu,Mn,Zn含量较高,其中Cu,Mn,Zn均主要以结合态形式存在。结论该实验所建立的HPLC-ICP-MS分析方法是太子参水提液中金属元素形态分析的良好方法。
Objective To develop a modern analysis method for speciation of metal elements （ Cu, Mn, Zn） in Taizishen. Methods The contents of three elements in Taizishen and the extract of Taizishen were determined by ICP - MS, and the coupling of high performance liquid chromatography （HPLC） with inductively coupled plasma mass spectrometry （ICP- MS） was applied for elemental speciation. Results In the extract of Taizishen, the contents of Cu, Mn, Zn were high, and the organic speciation of Cu, Mn, Zn were the main speciation. Conclusion The HPLC - ICP - MS method is efficient to separate inorganic speciation and organic speciation of the metal elements in Taizishen.
