摘要： 腺毛菊苣是新疆维吾尔族传统习用药材，但其药物中有效微量、常量元素成分尚未进行过分析研究。试验采用HNO3作为消解液，利用微波消解的方法处理样品，原子吸收分光光度法测定维吾尔药材菊苣根中钾(K)、镍(Ni)、钙(Ca)、镁(Mg)、铁(Fe)、锰(Mn)、铜(Cu)和锌(Zn)八种微量、常量元素的含量，精密度和回收率较好，回收率控制在92.25%～110.5%之间，相对标准偏差RSD≤3.88%。结果显示新疆菊苣中Mg, Ca, Fe, K等人体所需的必须微量元素含量十分丰富，特别是Mg和Ca含量较高，分别达到278.17和65.84 mg·g-1。其他元素中Mg和Zn含量中等;而Cu含量则较低，仅有0.016 5 mg·g-1，Ni含量为0.004 38 mg·g-1，实验结果为维吾尔医利用菊苣治疗心脑血管、骨质疏松症等疾病从微量元素的角度提供了有用的数据。

Abstract：The Cichorium glandulosum Boiss et Huet is a traditional Uighur natural herbal medicine, but has not been analyzed and studied in terms of its metal elements. In the experiment, the Cichorium glandulosum Boiss et Huet powder was digested with HNO3 by microwave digestion before determination. The eight metal elements, potassium, nickel, calcium, magnesium, iron, manganese, copper and zinc, in Cichorium glandulosum Boiss et Huet were determined by FAAS. The working conditions, accuracy and precision of the method were studied. The linear correlations of standard curves are good (r=0.999 1-0.999 9). The recovery (n=6) is 92.25%-110.5%, and the RSD (n=6) is 0.7%-3.88%. The results showed that there were comparatively rich metal elements, among which are comparatively high calcium (65.84 mg·g-1), iron (24.38 mg·g-1), magnesium (278.17 mg·g-1) and potassium (18.50 mg·g-1), in Cichorium glandulosum Boiss et Huet, and the contents of other elements are nickel of 0.004 38 mg·g-1, manganese of 0.52 mg·g-1, copper of 0.016 5 mg·g-1 and zinc of 0.18 mg·g-1. This provided useful data for discussing the relationship between the content of the metal elements in Cichorium glandulosum Boiss et Huet and its clinical application in cardiovascular and osteoporosis disease.
