Soil nutrients and inorganic elements affect not only the growth and development of medicinal plants but also the formation and accumulation of active ingredients in traditional Chinese medicines. The content of tanshinones and 28 inorganic elements in Salviae Miltiorrhizae Radix et Rhizoma samples from 18 producing areas in 6 provinces was determined, and 35 physical and chemical properties of the corresponding soil samples were determined. The enrichment characteristics of inorganic elements in Salviae Miltiorrhizae Radix et Rhizoma were analyzed. The correlation analysis and stepwise regression analysis were performed to screen out the main soil factors affecting the content of tanshinones in Salviae Miltiorrhizae Radix et Rhizoma. The results showed that the content of tanshinones in the samples from different areas varied significantly, being the highest in the samples from Shandong, the second in the samples from Henan, and low in the samples from Shanxi and Sichuan. K, Mg, Ca, and Na were rich in Salviae Miltiorrhizae Radix et Rhizoma samples, among which Na and K had the highest enrichment coefficients. The results of correlation and regression analyses showed that soil K, Na, Ti, and total nitrogen were the main soil factors affecting the tanshinones in Salviae Miltiorrhizae Radix et Rhizoma. Specifically, the content of tanshinones was positively correlated with Ti and negatively correlated with Na, K, and total nitrogen in the soil. Therefore, during the planting of Salvia miltiorrhiza, the land should be selected with full consideration to the salinity and saline land should be avoided. Secondly, the application of nitrogen and potassium fertilizers can be appropriately reduced, and water-soluble elemental fertilizers for S. miltiorrhiza should be developed.
土壤养分和无机元素不仅影响药用植物的生长发育，还影响中药材中活性成分的形成与积累。测定了6省18个产地丹参样品中丹参酮含量及28种无机元素，并测定了相应土壤样品的35项理化性质。分析了丹参中无机元素的富集特征。通过相关性分析和逐步回归分析，筛选出影响丹参中丹参酮含量的主要土壤因子。结果表明，不同产地样品中丹参酮含量差异显著，山东样品中含量最高，河南样品次之，山西和四川样品较低。丹参样品中富含钾、镁、钙和钠，其中钠和钾的富集系数最高。相关性和回归分析结果表明，土壤钾、钠、钛和全氮是影响丹参中丹参酮的主要土壤因子。具体而言，丹参酮含量与土壤中的钛呈正相关，与钠、钾和全氮呈负相关。因此，在丹参种植过程中，应充分考虑土壤盐分来选择土地，避免选择盐碱地。其次，可适当减少氮钾肥的施用，并研发丹参专用的水溶性元素肥料。
