| Abstract: | Objective The contents of Fe,Zn,Mg,Ca and Cu in sarcandrae herba were analyzed by flame atomic absorption spectrometry. Methods The samples were pretreated with HNO3-HClO4 and measured quantitatively through calibration curve method. Results It was shown that the samples has rich in human essential metal elements. The recoveries are between 99. 35% and 103. 30%,and the relative standard deviation is less than 5%. Conclusion The result measured by this method is considered to be accurate. |
