To research and screen the soil factors which influenced the quality of Panacis Majoris Rhizoma.
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.
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.
研究并筛选影响大叶三七质量的土壤因子。
通过测定不同产地大叶三七皂苷有效成分以及土壤养分和重金属含量，采用相关性分析、逐步回归分析等统计方法，分析土壤因子对大叶三七质量的影响。
不同产地样品中人参皂苷Ro和竹节人参皂苷NVa含量存在差异，相应土壤养分和重金属含量也不同。人参皂苷-Ro含量与土壤pH值呈正相关（P<0.01），与土壤有效氮呈负相关（P<0.05）。竹节人参皂苷IVa含量与土壤pH值（P<0.01）和铜含量（P<0.05）呈正相关，与土壤有效氮呈负相关（P<0.05）。结论：土壤因子是影响大叶三七质量的主导因素，土壤pH值和土壤有效氮是主要影响因素。
