title: [Determination of metallic elements in different parts of Salvia miltiorrhiza by FAAS].
abstract: 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.
