ICP-OES测定人参不同生育期的11种金属

Determination of 11 Metal Elements of Panax ginseng C.A.Mey in Different Growth Stages by ICP-OES

利用全谱直读电感耦合等离子体-发射光谱法(ICP-OES)测定了人参不同生育期(20、40、60、80、100、120d)Al、Co、Cr、Cu、Fe、Mg、Mn、Ni、Sn、V、Zn 11种金属含量。结果表明:人参体内Al、Fe、Mg、Mn、Zn等金属元素含量较高,微量元素Co、Cr、V等含量较少,Al、Cr含量在120d达到最高,Cu、Mg、Mn、Ni含量在40d达到最高,分别为10.13、1786.19、60.96、5.82μg/g;Co、Fe、Sn、V、Zn含量在100d最高,分别为0.31、380.73、8.49、0.72、50.98μg/g。

The contents of 11 metal elements（Al,Co,Cr,Cu,Fe,Mg,Mn,Ni,Sn,V and Zn） of Panax ginseng C.A.Mey in different growth stages（20,40,60,80,100,120d） were determined by inductively coupled plasma optical emission spectrometry（ICP-OES）.The contents of metal elements （Fe,Al,Mg,Mn,Zn） are rich,trace elements（Co,Cr,V） are low.The contents of Al and Cr were the highest in 120d,contents of Cu,Mg,Mn and Ni reached the highest in 40d（10.13,1786.19,60.96, 5.82μg/g,respectively）,contents of Co,Fe,Sn,V and Zn reached the highest in 100d（0.31,380.73, 8.49,0.72,50.98μg/g,respectively）.
