Abstract: 21 mineral elements of Rhodiola quadrifida from three populations in Qinghai province were determined by ICP-OES,including Be,Ca,Cd,Co,Cr,Cu,Fe,Li,Mg,Mn,Mo,Ni,Pb,Sb,Se,Sr,Ti,TI,V and Zn.The determined results showed that 18 mineral elements were detected in R.quadrifida from three populations,excepting Cd,Se and TI.Among the detected 18 elements,16 other mineral elements were detected in all three populations except Mo and Cu,and the average contents of 16 mineral elements were listed as follows:Ca>Mg>Fe>Ti>Sr>Mn>Cr>Zn>Li>V>Pb>Be>Sb>As>Ni>Co.Among which,Ca content was the highest,while Co content was the lowest.The content of different mineral element of R.quadrifida in three populations showed difference,of which Mn,Ti,Fe,V with larger variation coefficients.

Key words: ICP-OES, Rhodiola quadrifida, mineral element, trace element
