白刺在传统藏医用药、民间用药中均有广泛用途。利用220FS型原子吸收光谱仪测定了柴达木地区的唐古特白刺和西伯利亚白刺各部位中钾、钠、钙、镁、铜、锌、铁、锰8种矿物质元素。结果表明，两种白刺中矿物质元素含量各异，且因部位不同而异，但又呈观一定的规律性，除锌外，其它元素含量分布大致为叶>枝>果皮>果核>果汁，锌元素主要分布在枝和果核中。 |

Nitraria was widely used as the traditional Tibetan medicine and folk medicine. The content of 8 mineral elements such as K, Na, Ca, Mg, Cu, Zn, Fe and Mn in the different part of Nitraria sibirica Pall. and Nitraria tangutorum Bobr. in Tsaidam region was determined by 220FS atom absorption spectrometer. The results showed that 8 mineral elements content was differed in the two species, and so did in the different parts of the samples. However, to some extents, the content distribution of the mineral elements indicated a tendency except Zn: leaves>branches>rinds>seeds>juices. While Zn mainly distributed in branches and seeds. |
