Objective: To establish the correlation between the quality of Rhizoma Ligusticum Chuanxiong from different producing areas and soil factors

and find the main factors that influence the quality of Rhizoma Ligusticum chuanxiong. Method: TFW-VII soil nutrient and moisture tester was used to determine the content of organic matter

available P

available K and nitrate-nitrogen. SPSS statistical software was used to analyze the correlation between the soil nutrition values and the content of effective components in Rhizoma Ligusticum Chuanxiong. Result: The statistical results showed that the content of available K had obvious correlations with the content of effective components in Rhizoma Ligusticum Chuanxiong. The content of available K had a significant negative correlation with the content of total fluorescence materials and ligustilide

while it had a significant positive correlation with the content of senkyunolide. The second were organic matter

pH and available P

while the content of nitrate-nitrogen had no significant correlation with the effective components. Conclusion: The main soil factors to influence the content of effective components in Rhizoma Ligusticum Chuanxiong were available K and organic matter. The content of effective components had certain correlation with the soil nutrition values

that is to say the soil nutrient influenced on the quality of Rhizoma Ligusticum Chuanxiong is not single factor function

but synergistic effect. This conclusion can provide theory support for reasonable cultivation and maintenance of Rhizoma Ligusticum Chuanxiong.
