Objective: This study was to develop a method for determination of trace elements in Erythronium sibiricum's bulb. Method: An inductively coupled plasma mass spectrometry(ICP-MS) method was used for the determination of the contents of 12 trace elements in E. sibiricum's bulb after microwave digestion of the samples. Result: Satisfactory linearity of working curves for the 12 elements was obtained
with all the correlation coefficients over 0.999 3.The precision of measurement ranged from 1.45% to 3.58%.The recoveries of detection was in the range of 90.1% to 115.6%. The results showed that E. sibiricum's bulb contained rich trace elements
such as Fe
Al
Zn
Mn and Cu. Conclusion: The proposed method had the advantages of simplicity
speediness and sensitivity. It can satisfy the need for determination of trace elements.
