Variations of micro- and macrominerals concentration in Swertia speciosa were determined by atomic absorption spectroscopy. The mineral elements showed significant changes in roots and leaves collected from different altitudes. Among all the elements, highest concentration (more than 2,000 mg/kg) of Ca and K were recorded in S. speciosa and the concentration of other elements analyzed in the study decreased in the order Fe>Na>Zn>Co>Li>Cu>Mn.
原子吸收光谱法测定了獐牙菜中微量元素和宏量元素的浓度变化。从不同海拔采集的獐牙菜根和叶中的矿物质元素有显著变化。在所分析的元素中，Ca 和 K 的浓度最高（超过 2000mg/kg），其他元素的浓度顺序为 Fe>Na>Zn>Co>Li>Cu>Mn。
