| Abstract: | The Corydalis yahusuo samples were digested by concentrated nitric acid and concentrated hydrochloric acid(1:3,V/V),and the contents of trace elements,such as Fe,Mn,Cu and Zn,in the solution were determined by flame atomic absorption spectrometry(FAAS),then the results were compared and analyzed.The additional standard recoveries of method were from 99.7% to 102.3%with RSDs in the range of 0.5%—2.3%.The results have good accuracy and precision. |
