采用微波消解-ICP-AES技术, 测定了新疆不同产地天山花楸枝叶及果实中Ca, K, Mg, Na, Fe, Mn, Zn, Cu, Pb, As等十种元素的含量。 结果发现: 不同产地的天山花楸枝叶及果实中元素的含量均有差异, 枝叶中的含量较果实中的含量要丰富, 对人体有益的Ca, K, Mg, Na, Fe, Mn, Zn, Cu等元素的含量均较高, 有害元素Pb和As的含量较低。 实验结果为更好的开发和利用新疆天山花楸药用资源提供科学依据。

The contents of ten elements Ca, K, Mg, Na, Fe, Mn, Zn, Cu, Pb and As in branches and leaves and the fruits of Sorbus tianschanica Ruper. from different habitats in Xinjiang were determined by ICP-AES using microwave digestion. The study indicated that the contents of elements in branches and leaves and the fruits of Sorbus tianschanica Ruper. from different habitats in Xinjiang are different, and the contents of elements in branches are richer than that in the fruits of Sorbus tianschanica Ruper. The contents of Ca, K, Mg, Na, Fe, Mn, Zn, and Cu are all high, and the harmful elements such as Pb and As are low. The results provide scientific basis for the development and utilization of the medicinal resource of Sorbus tianschanica Ruper. in Xinjiang.
