    Abstract:
    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.
