摘　　要：本文利用湿法消解结合电感耦合等离子体发射光谱仪测定了六种绿绒蒿属药用植物中元素组成及含量,采用PC-ORD数据分析软件对数据进行聚类分析和DCA分析。结果显示,同一元素在不同绿绒蒿样品中显示出不同的含量水平,以含量排序,前6种元素均依次为K>Ca>Mg>Fe>Al>Na;聚类分析将六种绿绒蒿植物聚为三个类群,即五脉、川西、红花和全缘叶绿绒蒿为第一类群,多刺和总状绿绒蒿分别为第二和第三类群;DCA分析则显示采样点海拔与六种绿绒蒿植物中各元素的富集呈负相关影响,经纬度土壤pH值则与其呈正相关影响。本实验结果可为绿绒蒿属植物资源的深入研究和开发利用提供一定的科学依据。The contents of 15 elements in 6 Meconopsis species were determined by inductively coupled plasma optical emission spectrometer （ICP-OES）, and the data were analyzed by using PC-ORD data processing program. The results showed that these herbs were all rich in minerals but with a significant difference, and the major ones were in the order of K 〉 Ca 〉 Mg 〉 Fe 〉 A1 〉 Na. Based on the difference of the elements＇ contents, these tested samples were clustered into 3 groups, the first class contained Meconopsls quintuplinervia, M. henrici, M. punicea and M. integrifolia. The others were in the second （M. horridula） and the third （M. racemosa） team, separately. The elevation of sampling point was found to be inversely associated with the elements＇ concentration, and other 3 factors presented opposite influence,which indicated by the detrended correspondence analysis. These findings provided some theoretical basis for further study and application of these Meconopsis Vig. herbs.
