摘要: 采用ICP-OES对青海省3个居群四裂红景天中As、Be、Ca、Cd、Co、Cr、Cu、Fe、Li、Mg、Mn、Mo、Ni、Pb、Sb、Se、Sr、Ti、TI、V和Zn等21种矿物元素进行分析。结果显示,3个居群四裂红景天中矿物元素共检出18种,Cd、Se和TI 3种均未检出。除Mo和Cu外,其它16种矿物元素在3个居群中均有检出,平均含量排序为Ca>Mg>Fe>Ti> Sr>Mn>Cr>Zn>Li>V>Pb>Be>Sb>As>Ni>Co,其中,Ca含量最高,Co含量最低。3个居群四裂红景天矿物元素含量存在差异,Mn、Ti、Fe、V这4种矿物元素的变异系数较大。

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
