Abstract:
OBJECTIVETo determine the concentration of mineral elements and analyze the principal components in Thesium chinense.
METHODMineral elements were determined by ICP-DES. Principal components analysis (PCA) was used toanalyze and evaluate the characteristic elements.
RESULTT. chinense contained more than 17 mineral elements, Fe, Zn, Cu, Mn, Cr, Co, Ni, Sr, B, Ca, P, K, Na, Mg, Mg, Mn, Zn and Cu were abundance in T. chinense. The concentration of Mn and Zn were about 100 microg x g(-1), Mg was from 1 898.0 to 3 137.73 micro x g(-1), Fe > 500 microg x g(-1). PCA concluded that four factors (F1, F2, F3, F4 ) could be used to evaluate the quality of T. chinense. The function is following: F = 0.444 77F1 + 0.237 71F2 + 0.167 28F3 + 0.150 24F4. The scores of different populations of T. chinens were from 0.627 to 0.189. Zn,Cu,Mg,P, K, Al, Fe, Cr, Na, Co, Pb, Mn, B and Ca were the characteristic elements of T. chinense.
CONCLUSIONT. chinense contain more than 17 mineral elements. Zn, Cu, Mg, P, K, Al, Fe, Cr, Na, Co, Pb, Mn, B and Ca were the characteristic elements of T. chinense.
