| Abstract: | Objective] To determine the contents of Mn,Cu,Pb in Coptis chinensis by FAAS in Enshi,Hubei Province.Method]The samples were digested with the HNO3-HClO4 system and then the flame atomic absorption spectrometry was adopted to determine the contents of three mental elements（Mn,Cu and Pb） in Coptis chinensis from Enshi,Hubei Provence.Result]Coptis chinensis contains abundant mental elements,such as Mn（1 084.5 μg / g） and Cu（20.05 μg / g）.Pb is lower than determination limit.The additional standard recoveries of samples is between 99.1% and 105.5%.Conclusion]The method is of high sensitivity,good stability,precision and accuracy requirements,which can provide reference for further exploitation and utilization of Coptis chinensis resources. |
