摘要: 【目的】分析新疆精河枸杞中10种常量与微量元素的含量和初级形态,对于建立检测方法及确立精河枸杞中微量元素的存在形态和药用价值的研究具有一定的意义。【方法】 用0.45 μm滤膜和D101大孔吸附树脂分离提取液中的可溶态、悬浮态、有机态与无机态。对水煎渣依次用丙酮和盐酸进行提取,采用电感耦合等离子体质谱仪(ICP-MS)用ICP-MS对10种元素初级形态的含量进行测定。【结果】 精河枸杞中10种元素Mg、Zn、Ca、Fe、Cu、Mn、As、Se、Cd、Pb各个元素的提取率在20.5%~47.8%,10种常量与微量元素的相对标准偏差在0.12%~1.25%;回收率在84.60%~106.1%。【结论】该工作的研究对于建立检测方法及确立精河枸杞中微量元素的存在形态和药用价值的研究具有一定的意义。

Abstract: 【Objective】 Based on the medicinal value of Lycium barbarum, the contents and primary speciation of ten kinds of macro and trace elements in Jinghe wolfberry, Xinjiang, were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). 【Method】Water soluble、suspended, organic and inorganic states in extract solution were separated by 0.45 μm filter membrane and D101 macroporous adsorption resin. Water decoction residues were extracted by acetone and hydrochloric acid successively and the contents of the ten elements in different states were determined by ICP-MS.【Result】The relative standard deviation of ten elements of Mg , Zn , Ca , Fe , Cu , Mn , As , Se , Cd and Pb of the ten kinds of elements in the Jinghe Fructus Lycii was between 20.5% and 47.8% , and the relative standard deviation of them was 0.12%-1.25% ; The recovery rate was 84.60%-106.1%.【Conclusion】The study of this work has certain significance for the establishment of detection method and the determination of the form and medicinal value of macro and trace elements in Jinghe wolfberry (Lycium barbarum L.).
