title: [Characteristics of inorganic elements in Panacis Majoris Rhizoma and relationship with its Daodi habitat].
abstract: OBJECTIVE
  To investigate the Daodi habitat of Panacis Majoris Rhizoma by analyzing the characteristics of inorganic elements in Panacis Majoris Rhizoma from different habitats.
  
  
  METHODS
  The contents of inorganic elements in Panacis Majoris Rhizoma from different habitats were determined by ICP-AES. The characteristics of inorganic elements in Panacis Majoris Rhizoma were analyzed by correlation analysis, principal component analysis and cluster analysis.
  
  
  RESULTS
  It was showed that there was a correlation between the contents of inorganic elements and the medicine quality of Panacis Majoris Rhizoma; Fe, Cr, Al, Mg, Cd, Ca and Zn were principal components of Panacis Majoris Rhizoma; and the contents of inorganic elements in Panacis Majoris Rhizoma existed regional differences.
  
  
  CONCLUSIONS
  The contents of inorganic elements Ca, Fe and Zn,especially the content of the essential trace elements Fe and Zn, can be used as one of the key reference for medicinal quality evaluation of Panacis Majoris Rhizoma; as well, Shaanxi Province is probably the Daodi habitat of Panacis Majoris Rhizoma.
