摘　　要：通过采用ICP-MS检测了柴达木盆地3种不同颜色果实唐古特白刺叶中11种矿物质元素.结果表明不同颜色果实唐古特白刺叶中矿物质元素存在差异.唐古特白刺叶中常量元素以Na元素最高,其中以紫色果实白刺叶中Na元素和常量元素总量最高,大红果白刺叶最低.微量元素在白刺叶中以Fe元素含量最高,其中以紫红果白刺叶中Fe元素和必需微量元素总量最高,紫色果含量最低.另外,有害元素Pb和Cd在3种颜色果实的叶子中含量均较低.方法简便快速,结果准确可靠,可以为不同颜色果实唐古特白刺叶子的应用提供基础数据.Eleven mineral elements of the Nitraria tangutorum Bobr. leaves of three different colorful fruits in Qaidam basin were analyzed by ICP-MS. The results showed that differences exist among the contents of these elements in the Nitraria tangutorum Bobr. leaves of different colorful fruits. The highest content of major elements is Na. Among them, the highest contents of total major elements and Na both exist in the leaves of purple fruits. Whereas, the lowest amounts of them are in the leaves of red fruits. As for the trace elements, Fe is in relatively higher amount. The highest and lowest contents of the total trace elements and Fe exist in the leaves of prunosus and purple fruits, respectively. In addition, the contents of hazardous elements （Pb and Cd） in the leaves of three different colorful fruits are low. The experimental method is simple, rapid, accurate and reliable, and can provide basic data for the application of Nitraria tangutorum Bobr. leaves of different colorful fruits.
