| Abstract: | OBJECTIVE：To determine the content of trace elements in Euphrasia regelii.METHODS：A concentrated nitric acid and perchloric acid（4：1,V：V） mixture solution was used to digest the herbal sample,and flame atomic absorption spectrometric（FAAS） was applied to determine the content of trace elements（Fe,Cu,Zn,Mn）.RESULTS：The contents of trace elements（Fe,Cu,Zn,Mn） in E.regelii were 739.84 μg·g-1,16.04 μg·g-1,108.86 μg·g-1 and 49.20 μg·g-1,respectively.Average recoveries were 97.6%～103.0%,and RSD ranged 0.8%～3.5%（n=6）.CONCLUSION：E.regelii contains rich trace elements（Fe,Cu,Zn,Mn）.The method is simple and accurate,and trial result can provide reference for the further study of pharmacological action of E.regelii. |
