ObjectiveTo study the correlation between the content of active ingredients of Aurantii Fructus in different main production areas and soil factors， so as to provide a theoretical basis for implementing ecological regulation of soil， improving the quality of Aurantii Fructus， and revealing the origin of genuine medicinal materials. MethodThe content of naringin， neohesperidin， total flavonoids， volatile oil， total nitrogen， total phosphorus， total potassium， and 17 soil factor-related indicators in 25 batches of Aurantii Fructus from different production areas were determined. The main soil factors affecting the content of active ingredients of Aurantii Fructus were analyzed by Pearson correlation analysis， principal component analysis， and grey correlation analysis. ResultThe pH value of the soil is between 4.83 and 8.21， and the soil is weakly acidic and neutral in general. Soil fertility exceeds the average. Pearson correlation analysis shows that the soil factors most related to the four active ingredients of Aurantii Fructus are total phosphorus， available copper， available zinc， exchangeable magnesium， available sulfur， available phosphorus， and available molybdenum. Principal component analysis shows that total nitrogen， alkali-hydrolyzable nitrogen， organic matter， available phosphorus， and available zinc are the main characteristic factors in soil. Grey correlation analysis shows that the main soil factors affecting the active ingredients of Aurantii Fructus are total phosphorus， total nitrogen， available zinc， available copper， exchangeable magnesium， and pH. ConclusionIn the cultivation of Aurantii Fructus， the medicinal material quality of Aurantii Fructus could be improved by adjusting the level of beneficial factors in the soil and improving the soil texture.
