| Abstract: | The contents of three trace elements （Fe,Ca and Cu） in Schizonepeta from Enshi were determined by flame atomic absorption spectrometry after digested with HNO3-HClO4. The results showed the contents of trace elements in Schizonepeta were higher with Fe of 1099 μg·g^-1,Ca of 21 860 μg·g^-1 ,Cu of 11. 44 μg·g^-1. The additional standard recovery of samples was 99.1%- 105.0%. The method is rapid, simple, accurate,and sensitive. It provides reference for pharmacological action research of Schizonepeta. |
