目的分析林下山参与园参中无机元素特征。方法采用电感耦合等离子质谱(ICP-MS)法测定林下山参和园参药材中无机元素的量,分别建立林下山参和园参的无机元素标准谱,运用SPSS 15.0统计软件对结果进行统计分析。结果聚类分析将17份样品聚为林下山参和园参两大类,主成分分析选出3个主成分,得出林下山参与园参的特征元素为Ca、Na、Fe、Zn、Cu、Mo、V、Sn、Sr、Al、Ba、Ge。元素的分布特征与人参的生态环境、栽培方式及生长年限有关。结论主成分分析法和聚类分析法是林下山参与园参药材中无机元素分析的有效方法。

Objective To explore the characteristics of inorganic elements in commercial ginseng cultivated in forest and garden. Methods The contents of inorganic elements in commercial ginseng cultivated in forest and garden were determined by ICP-MS. The reference diagram for inorganic elements in commercial ginseng cultivated in forest and garden was established. The statistic analysis was completed by SPSS 15.0 software. Results Cluster analysis showed that 17 samples could be clustered reasonably into two groups. Three principal components were extracted. The results showed that Ca, Na, Fe, Zn, Cu, Mo,Sn, Sr, Al, Ba, and Ge were the characteristic elements in commercial ginseng cultivated in forest and garden. The element distribution characteristics were related to the ecological environment, cultivation methods, and growth years. Conclusion The cluster analysis and principal component analysis are effective methods for inorganic elements analysis.
