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
