摘　　要：对高原香薷、萼果香薷、密花香薷、细穗香薷等四种药用香薷植物中的17种微量元素含量进行了测定和分析。结果表明,4种香薷植物中常量元素以K含量最高,其次为Ca、Mg、Na;必需微量元素中以Cu、Fe、Mn元素的含量为高;非必需微量元素As、Hg、Pb、Cd、Sb含量较低,从重金属元素的角度考虑,使用所测定的4种香薷植物是安全的。＂Xiangru＂, belonging to the Elsholtzia genus of the Labiatae family, was used as an important and traditional medicine plant for a long time. 17 trace elements had been analyzed in four species of Elsholtzia, Elsholtzia feddei Benth. , E. densa Diels, E. densa Benth. , and E. densa Maxim. And levels of trace elements was also evaluated and compared among the four species. The results indicated that the content of macro - elements K, Ca, Mg, Na and essential trace elements Cu, Fe, Zn, Mn, Co, Ni, Se in Elsholtzia species was abundant, especially focused on the macro - elements K and the essential trace elements Cu, Fe and Mn. The content of non - essential trace elements As, Hg, Pb, Cd, Sb in four species of Elsholtzia was lower for the safety of therapy.
