| 中文摘要:目的 研究甘肃民乐黄芪品质与土壤的关系。方法 采集黄芪药材和土壤样品，利用高效液相色谱法、紫外分光光度法、原子吸收分光光度法等测定药材质量、土壤因子及重金属元素。结果 民乐黄芪质量符合药典标准规定，受重金属污染风险低。浸出物与速效钾呈显著负相关；黄芪甲苷与速效钾呈显著正相关；毛蕊异黄酮葡萄糖苷与可溶盐呈极显著正相关，与速效钾呈显著正相关，与pH值呈显著负相关。其中，土壤pH值是影响黄芪浸出物、黄芪甲苷、毛蕊异黄酮葡萄糖苷三者含量的关键因素，其次为全磷、有机质和全氮。结论 研究结果揭示了土壤因子是民乐黄芪品质的主要影响因素，可为民乐县规范化种植黄芪药材提供理论依据。 |

| Abstract:Objective To study the relationship between the quality of Astragalus membranaceus and soil in Gansu Minle.Methods we sampled the medicinal materials and soils of Astragalus membranaceus in Minle County, and determined the medicinal quality, soil factors and heavy metal elements by high performance liquid chromatography, ultraviolet spectrophotometry, atomic absorption spectrophotometry, and etc.Results The quality of Minle Astragalus meets the requirements of the Pharmacopoeia standards and is low on the risk of heavy metal pollution. There was a significant negative correlation between the extract and the available potassium. There was a significant positive correlation between the astragaloside IV and the available potassium. There was a highly significant positive correlation between calycosin-7-glucoside and soluble salt. There was a significant positive correlation with available potassium, and a significant negative correlation with pH. Among them, soil pH value is the most important factor affecting the content of astragalus extract, astragaloside IV and verrucous glucoside, followed by total phosphorus, organic matter and total nitrogen.Conclusion The results revealed that the soil factors is the main influencing factor of the quality of Astragalus membranaceus in Minle County, which can provide a theoretical basis for the standardized cultivation of Astragalus membranaceus in Minle County. |
