[Determination of elements in branches and leaves and the fruits of Sorbus tianschanica Ruper. from different habitats in Xinjiang by microwave digestion-ICP-AES].

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.
