摘要： 以甘肃不同产地黄管秦艽为材料，测定其无机元素含量，分析黄管秦艽中无机元素特征及评价药材质量。采用火焰原子吸收光谱法测定黄管秦艽中无机元素含量，并运用相关性分析和主成分分析对其含量进行分析和评价。结果表明不同产地黄管秦艽中无机元素Ca、K、Mg、Mo含量较高，部分无机元素之间存在相关性；经主成分分析得到3个主因子，3个主成分的累计方差贡献率为83.20%。从无机元素含量的主成分分析来看，产于卓尼县尼巴乡的黄管秦艽质量最优，本实验可为黄管秦艽的资源开发利用、质量控制以及安全评价提供参考依据。

关键词: 黄管秦艽, 无机元素, 相关性分析, 主成分分析

Abstract: In this study,10 samples of Gentiana officinalis H.Smith.from different areas in Gansu province were used as research materials,to explore the characteristics of inorganic elements using flame atomic absorption spectrometry.In addition,principal components analysis and correlation analysis were further applied to analyze and evaluate the contents of inorganic elements.The analysis result showed that the contents of Ca,K,Mg and Mo were higher in G.officinalis from different areas.There was a correlation between some inorganic elements;Three principal divisors were gained in the principal component analysis,The contribution rate of accumulative variance of the three principal divisors was 83.20%.The quality of G.officinalis from Nipah Zhuoni County Township was best from the perspective of inorganic elements.This study on inorganic elements in G.officinalis can be used to provide guidance for the quality control and safety evaluation.

Key words: Gentiana officinalis H.Smith., inorganic element, correlation analysis, principal component analysis
