| 摘 要： | 采用电感耦合等离子体质谱(ICP/MS)法测定了12个西洋参样品中18种无机元素的含量,建立西洋参无机元素指纹谱,并用SPSS主成分分析法对西洋参中的特征元素进行分析;主成分分析选出五个主因子,得出西洋参的特征元素为Fe,Al,V,Mn,Mg,Sr,Mo,Ca,Cu;聚类分析将12个西洋参样品聚成五大类,表明元素的分布特征与西洋参的品种关系显著;主成分分析法和聚类分析法是西洋参无机元素分析的有效方法.

| Abstract: | The contents of elements such as Mg, A1, P, Ca, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Cd and Pb in twelve Panax quinquefolium. L samples were determined by means of ICP/MS. The results were used for the development of element fingerprint chromatogram. The principal component analysis of SPSS was applied for the study of characteristic elements in Panax quinquefolium. L Five principal components which accounted for over 90% of the total variance were extracted from the original data. The analysis results show that Fe, Al, V, Mn, Mg, Sr, Mo, Ca and Cu may be the characteristic elements in Panax quinquefolium. L The results of Q-type cluster analysis show that the samples could be clustered reasonably into five groups, and the elemental distribution characteristics are related to the breeds of Panax quinquefoliurn.
