The root, stem and leaf of Salvia miltiorrhiza were digested with HNO3-HClO4 (4:1), and the contents of five metallic elements such as K, Cu, Zn, Fe and Mg were detected by flame atomic absorption spectrophotometry. The recovery ratio by standard addition is 99.7%-104.4% and RSD is less than 2%. It was found that the content sequence of metallic elements is as follows: K>Mg >Fe>Zn>Cu. K, Cu, Zn, Fe and Mg in the leaf are clearly richer than those in the root and stem. The content ratio of Zn to Cu is relatively lower than that in the terrestrial angiosperms. The results provide a useful data for discussing the relationship between the contents of these elements in Chinese medicinal herb Salvia miltiorrhiza and the medical effects. Furthermore they also provide a data for the distribution of these elements in different parts of Salvia miltiorrhiza.
将丹参的根、茎、叶用硝酸-高氯酸(4:1)消解,采用火焰原子吸收分光光度法测定钾、铜、锌、铁、镁5种金属元素的含量。标准加入法回收率为99.7%-104.4%,相对标准偏差小于2%。结果表明,金属元素含量顺序为:钾>镁>铁>锌>铜。叶中钾、铜、锌、铁、镁含量明显高于根和茎。锌与铜的含量比值相对低于陆地被子植物。研究结果为探讨中药丹参中这些元素的含量与药理作用之间的关系提供了有用的数据。此外,也为这些元素在丹参不同部位的分布提供了数据。
