分析不同产地珠子参中微量元素的含量变化情况。应用电感耦合等离子体-原子发射光谱法(ICP-AES)测定不同产地珠子参中Ca、Cr、Cu、Fe、Ga、Li、Mg、Mn、Ni、Sn、Sr、Ti、Tl、V、Zn、Pb 16种微量元素的含量。结果表明,不同产地珠子参中各微量元素含量有所差异,陕西宁强产珠子参中Ca、Mg、Mn、Zn、Cu等含量高于其他产地。珠子参中微量元素的含量与产地的土壤、水质等有关。
Analysis of the changes in the content of trace elements in Beads ginseng from different areas. Determination of Ca, Cr, Cu, Fe, Ga, Li, Mg, Mn, Ni, Sn, Sr, Ti, Tl, V, Zn in beads from different areas by inductively coupled plasma-atomic emission spectrometry , Pb 16 kinds of trace elements content. The results showed that the contents of trace elements in Begonia grosvenorii from different areas were different. The contents of Ca, Mg, Mn, Zn and Cu in Begonia grosvenorii in Shaanxi were higher than those in other areas. Bead ginseng trace elements in the content and origin of the soil, water quality and so on.
