摘要

This work investigated the influence of soil physical and chemical properties on the accumulation of major active compounds in Epimedium species—such as epimedin and epimedium flavonoids—under different growth environments. Samples were collected from Qiandongnan Miao and Dong Autonomous Prefecture in Guizhou Province. Key soil parameters, including bulk density, porosity, and nutrient content, were analyzed to assess their effects on the accumulation of active components in Epimedium. The results revealed significant variations in soil physicochemical properties across different habitats, which in turn exerted a substantial impact on the biosynthesis and accumulation of bioactive constituents. The average content of active compounds was 4.37% in wild-grown Epimedium, 10.19% in field-cultivated plants, and 8.95% in forest-grown plants. Correlation analyses, including principal component analysis (PCA) and redundancy analysis (RDA), elucidated the complex relationships between soil environmental factors and the accumulation of active components. These findings provide a theoretical foundation for the artificial cultivation of Epimedium, offer technical guidance for optimizing cultivation practices and improving medicinal quality, and hold significant implications for the sustainable development of the Epimedium industry.
