Abstract

To analyze the iron,zinc,manganese in maozhaocao capsule,for its medical research to improve reference,the content of 3 trace elements in maozhaocao capsule was analysed by air-acetylene fire atomic absorption spectrometry(FAAS).The results show that the content of Fe is 287.8 μg/g,Zn is 27.4 μg/g,Mn is 24.6 μg/g,the relative standard deviation are within 2.67%～4.09%.The recoveries of elements are within 96.3%～107.6%.It concluds the content of Fe,Zn,Mn in Maozhaocao capsule of the method is accuracy and satisfactory.
