摘　　要：中药含有丰富的无机元素,特别是人体必需的无机元素含量较高。在样品中加入混酸,再用微波消解技术消化样品,采用火焰原子吸收光谱法对五种不同品种郁金(温郁金、姜黄、广西莪术、蓬莪术和川郁金)所含有的八种具有重要生理功能的无机元素——钾、钙、钠、镁、锌、铁、铜和锰的含量进行了测定。结果显示郁金类中药材含有相近的元素成分,不同来源的品种在个别元素含量上存在差异。基于各样品所含无机元素采用聚类分析进行相关性分析,药典所收载四种郁金(温郁金、姜黄、广西莪术和蓬莪术)聚为一类,与非正品川郁金有所区别,该聚类结果与依据形态特征的传统分类学结果一致。测定结果可为郁金中无机元素与其药效的相关性提供科学依据。Traditional Chinese medicine materials （TCM） contained abundant trace elements needed in human body. Mixed acid （HNO3∶HClO4） was added into samples treated by microwave digestion, and a systematic study was carried out by selection of the most appropriate working conditions and optimization of the sample mass. Some inorganic elements in 5 kinds of radix curcumae （Curcuma wenyujin Y. H. Chen et C. Ling, Curcuma longa L., Curcuma kwangsiensis S. G. Lee et C. F. Liang, Curcuma phaeocaulis Val. and Curcuma chuanyujin C. K.Hsieh et H. Zhang） necessary to lives were determined by flames atomic absorption spectrometry （AAS）. Elements, such as K, Ca, Na, Mg, Zn, Fe, Cu and Mn were detected. The results show that there are similar elements in the five kinds of radix curcumae, while differences only exist in a few elements contents. The correlative analysis of trace elements in samples was carried out by cluster analysis of the 4 kinds of radix curcumae （Curcuma wenyujin Y. H. Chen et C. Ling, Curcuma longa L., Curcuma kwangsiensis S. G. Lee et C. F. Liang and Curcuma phaeocaulis Val.） in codex populations in a cluster, different from the unofficial sample （Curcuma chuanyujin C. K. Hsieh et H. Zhang）. The cluster analysis results are consistent with the morphological characteristics of the traditional taxonomy results. The results showed that the analytic method is advisable. This paper provides scientific basis for deeply studing the relation between trace elements and drug effect of radix curcumae.
