摘　　要：采用ICP-MS电感耦合等离子体质谱仪,对选自8个省份不同生长环境下的龙葵药材中17种无机元素进行了测定和分析,利用SPSS统计软件对龙葵药材中无机元素进行主成分分析和聚类分析。各产地的龙葵中元素的绝对含量虽然不同,但却呈现相似的分布态势。主成分分析结果表明:B、V、Fe、Co、As、Se、Sr、Mn、Cu、Zn、Rb、Ni、Si、Mo为龙葵药材的特征元素。聚类分析结果表明元素的分布特征与龙葵药材的生长环境密切相关。主成分分析和聚类分析是龙葵药材元素分析的有效方法。为寻找影响龙葵药材质量的因素提供帮助。Using ICP-MS inductively coupled plasma mass spectrometer,selected from six provinces of the different growth environments of 17 herbs nigrum inorganic elements were determined and analyzed using SPSS statistical software nigrum inorganic elements in medicinal herbs in the principal component analysis and cluster analysis.Principal component analysis results showed that：B,V,Fe,Co,As,Se,Sr,Mn,Cu,Zn,Rb,Ni,Si,and Mo for the medicinal characteristics of elements of Solanum nigrum.Cluster analysis results showed that the distribution of elements in the growth of herbs and black nightshade are closely related to the environment.Principal component analysis and cluster analysis is the analysis of Solanum nigrum medicinal elements in an effective manner.Solanum nigrum in search of medicinal herbs affect the quality of the factors that help.
