摘  要:
采用电感耦合等离子体原子发射光谱仪,对全国7个主要产地的26个山银花样品中的10种金属元素的含量进行定量分析,应用主成分分析和聚类分析对山银花资源中金属元素进行评价。结果表明:Pb、As、Fe、Ca、Zn、Mg、Mn、Cu、Cd、Cr的平均含量分别为0.25、0.065、77.9、3 277.1、31.0、2 244.7、319.9、14.6、0.31、0.217 mg/kg;主成分分析得出3因子模型,可解释实验数据的88.58%;主成分分析将26个山银花样品划分为4类,聚类分析显示了相似的结果。研究得出山银花中金属元素的含量分布特征,为山银花资源的品质评价和质量控制提供实验依据。

摘  要:
The contents of 10 metal elements(Pb, As, Fe, Ca, Zn, Mg, Mn, Cu, Cd and Cr) in 26 Flos Lonicerae samples collected from 7 different main growing regions were determined by inductively coupled plasma-atomic emission spectrometry. The metal elements in Flos Lonicerae were analyzed by principal component analysis(PCA) and cluster analysis(CA). The results showed that the average contents of Pb, As, Fe, Ca, Zn, Mg, Mn, Cu, Cd and Cr in Flos Loniceraewere 0.25, 0.065, 77.9, 3 277.1, 31.0, 2 244.7, 319.9, 14.6, 0.31 and 0.217 mg/kg, respectively. A three-factor model was obtianed by PCA, which could explain 88.58% of the experimental data.Tweenty-six Flos Lonicerae samples were classi?ed into four groups by PCA, which were similar to CA results. The regional characterization of metal elements provided references for quality evaluation and identification of Flos Lonicerae.
