| 摘要: |
| 为了探究陕南地区土壤因子对金银花有效成分积累的影响，该研究测定了陕南不同产地27批次金银花样品中绿原酸、3,5-二-O-咖啡酰奎宁酸、4,5-二-O-咖啡酰奎宁酸、总酚酸类、木犀草苷的含量及12种无机元素的含量，同时对金银花种植土壤12种无机元素的含量及5个肥力指标进行了测定，分析了金银花对无机元素的富集特征，筛选了影响金银花有效成分的主导因子。结果表明：（1）金银花酚酸类有效成分与土壤中Se、有机质呈正相关，与土壤中Co、Fe、Mn呈负相关。（2）金银花对土壤中各元素富集系数的趋势为Cd＞Cu＞Zn＞Se＞Ni＞Mn＞Hg＞Cr＞Co＞As＞Pb＞Fe，金银花质量控制需加强对药材中Cd含量的监控。（3）安康富Se地区具有种植开发富Se金银花的潜力，需同时关注土壤、金银花中Se与Cd的含量。综上认为，在金银花生产实践中可以提高增施有机肥、Se肥提高有效成分含量，该研究可为当地金银花药材规范化种植、富Se金银花开发提供指导。 |

| Abstract: |
| To investigate the impact of soil factors on the accumulation of effective components in Lonicerae Japonicae Flos in southern Shaanxi region, this study measured the content of chlorogenic acid, 3,5-di-O-caffeoyl quinic acid, 4,5-di-O-caffeoyl quinic acid, total phenolic acids, galuteolin, and 12 inorganic elements in 27 batches of Lonicerae Japonicae Flos samples from different production areas in southern Shaanxi. Additionally, the content of 5 fertility indicators and 12 inorganic elements in the corresponding planting soil were measured. The enrichment characteristics of inorganic elements in Lonicerae Japonicae Flos were analyzed, and the main factors affecting the effective components of Lonicerae Japonicae Flos were identified. The resultswere as follows: (1) Pearson correlation analysis revealed a positive correlation between the effective components of phenolic acids in Lonicerae Japonicae Flos with Se and organic matter in soil, while showing a negative correlation with Co, Fe, and Mn in soil. (2) The trend of element enrichment coefficients in soil by Lonicerae Japonicae Flos was as follows: Cd>Cu>Zn>Se>Ni>Mn>Hg>Cr>Co>As>Pb>Fe. Monitoring Cd element content in Lonicerae Japonicae Flos was crucial for cultivation. (3) The Se-abundant areas in Ankang show potential in Se-abundant Lonicerae Japonicae Flos development. The contents of Se and Cd in soil, Lonicerae Japonicae Flos should be expressed concerns at the same time. These results indicated applying organic and Se fertilizer in soil can improve the effective components in Lonicerae Japonicae Flos. The study can provide theoretical direction for standardized planting and Se-abundant product development of Lonicerae Japonicae Flos. |
