摘　　要：目的分析野生与栽培何首乌中无机元素的差异。方法用电感耦合等离子体质谱(ICP-MS)技术分析野生与栽培何首乌中24种无机元素;数据处理用SIMCA-P 11.5软件进行统计分析。结果主成分得分图显示,野生与栽培何首乌中无机元素差异明显,通过载荷图筛选出差异显著的10种无机元素,野生与栽培何首乌中10种差异无机元素呈现出不同的规律。结论揭示野生与栽培何首乌中无机元素的分布规律,为何首乌药材的质量控制及安全性评价提供参考依据。OBJECTIVE To analyze the differences of inorganic elements between wild and cultivated Polygonurn Multiflo- rum. METHODS Inductively coupled plasma mass spectrometry （ICP-MS） technology was applied to analyze 24 kinds of in organic elements between wild and cultivated Polygonum Multiflorum. SIMCA-P 11.5 software was utilized for data process- ing and statistical analysis. RESULTS The principal component score plot displayed the inorganic elements between wild and cultivated Polygonurn Multi florum existed significant differences. 10 inorganic elements with significant differences were screened by load diagram, which exhibited different patterns between wild and cultivated Polygonum Multiflorum. CONCLU- SION Our research reveals the distribution of inorganic elements between wild and cultivated Polygonum Multiflorum, which provides a normative reference for quality control and safety evaluation.
