title: [Influence of soil factors on quality of panacis majoris rhizoma].
abstract: OBJECTIVE
  To research and screen the soil factors which influenced the quality of Panacis Majoris Rhizoma.
  
  
  METHODS
  By determining the effective constituent of saponin of Panacis Majoris Rhizoma from different habitats, and the soil nutrient and heavy metal content, using correlation analysis, stepwise regression analysis and other statistical methods to analyze the soil factors on the quality of Panacis Majoris Rhizoma.
  
  
  RESULTS
  The contents of ginsenoside Ro and chikusetsusaponin NVa of samples from different habitats were different, the corresponding soil nutrient and heavy metal content were also different. The content of ginsenoside-Ro was positively related with the soil pH value (P <0. 01) and negatively related with the soil available N(P < 0.05). The content of chikusetsusaponin IVa was positively related with the soil pH (P < 0.01) and copper content (P < 0.05), and negatively with the soil available N(P < 0.05) CONCLUSION: Soil factors are the leading factors that influence the quality of Panacis Majoris Rhizoma, soil pH and soil available N were the dominating factors.
