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 Al, Co, Cr, Cu, Fe, Mg and Mn in ginseng at different growth stages (20, 40, 60, 80, 100 and 120 d) were determined by ICP-OES with full spectrum direct reading ICP-OES , Ni, Sn, V, Zn 11 kinds of metal content. The results showed that the contents of Al, Fe, Mg, Mn, Zn and other metal elements were high in the body of ginseng, while the contents of trace elements such as Co, Cr and V were less. The content of Al and Cr reached the highest in 120d, Reaching the peak at 40 days, reaching 10.13, 1786.19, 60.96 and 5.82 μg / g, respectively. The contents of Co, Fe, Sn, V and Zn were the highest at 100d, which were 0.31, 380.73, 8.49, 0.72 and 50.98μg / g, respectively.
