| 摘 要： | 应用全谱直读等离子体发射光谱法（ICP—AES）对不同居群达乌里秦艽（Gentiana dahurica Fischer）中15种元素含量进行了测定，通过聚类分析和主成分分析探讨了其化学元素特征及与生态环境的关系，为深入认识该药材的元素特征及其功效提供参考。结果表明，达乌里秦艽药用部位元素含量较丰富，以大量元素K，Ca和Mg含量较高。不同居群元素含量水平显示出地理分布差异特点；且各元素之间具一定的协调促进或拮抗作用，这种作用在聚类分析中再次得到证明；主成分分析的结果表明，其元素特征可用“代谢增强”作用因子和“酶活促进”作用因子来体现。海拔对两个因子有正向促进作用；经纬度则对前者具负向影响，对后者具正向影响。
