摘要(Abstract):

目的:探讨=牛儿苗中无机元素的特征。方法:采用电感耦合等离子体质谱(ICP/MS)法测定了10个=牛儿苗样品中24个无机元素的含量,建立=牛儿苗无机元素指纹谱,并用SPSS方差分析和主成分分析对=牛儿苗中的特征元素进行评价。结果:主成分分析选出5个主因子,得出=牛儿苗的特征元素为铝(Al),铊(Ti),钡(V),铁(Fe),镧(La),铈(Ce),锂(Li),镓(Ga),钯(Ba);聚类分析将10个=牛儿苗样品聚为2大类,结果表明元素的分布特征与=牛儿苗的生态和产地呈一定的相关性。结论:主成分分析法和聚类分析法是=牛儿苗无机元素分析的有效方法。
Objective:To explore the characteristics of inorganic elements in Erodium stephanianum.Method:The content of elements such as Li,B,Na,Mg,Al,Si,K,Ca,Ti,V,Cr,Mn,Fe,Ni,Cu,Zn,Ga,Br,Rb,Sr,Ba,La,Ce and Rb in ten E.stephanianum samples were determined by means of ICP/MS.The results were used for the development of element distribution diagram.The principal component analysis of SPSS and Q-type cluster analysis were applied for the study of characteristic elements in E.stephanianum.Result:Five principal components which accounted for over 91% of the total variance were extracted from the original data.The analysis results showed that Al,Ti,V,Fe,La,Ce,Li,Ga and Ba may be the characteristic elements in E.stephanianum;The results of Q-type cluster analysis showed that the samples could be clustered reasonably into two groups,and the elemental distribution characteristics were related to the ecology and origins of E.stephanianum.Conclution:The principal component analysis and Q-type cluster analysis could be used in data processing in inorganic elements.
