【摘要】 [Objective] The aim was to establish a method to determine the contents of trace elements in the wild and planted Rhodiola. [Method] The inductively coupled plasma mass spectrometer (ICP-MS) was adopted to determine and analyze several trace elements in the wild and planted Rhodiola. [Result] Under the selected experimental conditions, the detection limit was 0.002-0.092 ng/ml, the relative standard deviation (RSD) was between 1.87% and 4.96%, and the recovery rate of standard addition was 94.0%-104.5%. [Conclusion] The gross content of trace elements was higher in the wild Rhodiola than in the planted Rhodiola, but the contents of harmful elements such as Pb, As and Cd in wild Rhodiola were lower.
