Abstract

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.

摘要

采用微波消解-电感耦合等离子体发射光谱法（ICP-AES）测定了新疆不同产地天山花楸枝叶及果实中钙（Ca）、钾（K）、镁（Mg）、钠（Na）、铁（Fe）、锰（Mn）、锌（Zn）、铜（Cu）、铅（Pb）和砷（As）10种元素的含量。研究表明，新疆不同产地天山花楸枝叶及果实中元素含量存在差异，且枝叶中元素含量高于果实。其中，Ca、K、Mg、Na、Fe、Mn、Zn和Cu含量均较高，Pb和As等有害元素含量较低。该研究结果为新疆天山花楸药用资源的开发利用提供了科学依据。
