目的:测定野生羌活和宽叶羌活根、茎、叶、叶柄和种子中Ca、Mg、Fe、Mn、Cu、Zn 6种微量元素的含量。方法:采用空气-乙炔火焰原子吸收光谱法测定不同部位微量元素的含量,应用SPSS 16.0分析软件对结果进行统计分析。结果:相同部位不同元素的含量存在差异,野生羌活和宽叶羌活同一部位均以Ca元素含量最高,Cu、Zn元素含量最低。同种元素在不同植物不同部位中的含量也有差异,野生羌活Ca元素以叶片中含量最高,种子中含量最低;Mg、Cu、Zn元素以叶柄中含量最高,根和种子中含量最低;Fe元素以茎中含量最高,叶柄中含量最低;Mn元素以叶片中含量最高,茎中含量最低。野生宽叶羌活Ca元素以叶片含量最高,根中含量最低;Mg、Mn、Zn元素的含量以叶片中最高,茎中含量最低;Cu元素以叶中含量最高,根和叶柄中含量最低;Fe元素以根中含量最高,茎和种子中含量最低。结论:从微量元素角度分析,野生羌活和宽叶羌活的叶片、叶柄和种子等部位具有潜在的药用价值,可为综合开发利用有限的野生羌活药材资源提供一定的参考。
Objective: To determine the contents of six trace elements Ca, Mg, Fe, Mn, Cu, Zn in wild and notopted Rhizoma et Radix Notopterygii and its roots, stems, leaves, petioles and seeds. Methods: The contents of trace elements in different parts were determined by air-acetylene flame atomic absorption spectrometry. The results were analyzed by SPSS 16.0 software. Results: The contents of different elements in the same part were different. The contents of Ca, Zn and Cu were the highest in the same part of wild Notopterygium and Tripterygium. The contents of Ca, Cu, Zn were the highest in the leaves and the lowest in the seeds. The contents of Mg, Cu and Zn were the highest in the petioles and the lowest in the roots and seeds. The contents of Fe, The highest content in the stem, the lowest content in the petiole; Mn element to leaves the highest content, the lowest content in the stem. The contents of Ca, Mn and Zn were the highest in leaves and lowest in stems. The contents of Cu were the highest in leaves and the lowest in roots and petioles. Fe The elements are highest in roots and lowest in stems and seeds. Conclusion: From the perspective of trace elements, the contents of the leaves, petioles and seeds of wild notopterygium and broad leave and notopterygii have potential medicinal value, which may provide some reference for the comprehensive exploitation and utilization of wild and notopterygii medicinal resources.
