[Determination of Trace Elements in Different Parts of Boju and Root Soil by ICP-MS]

To explore the contents and enrichment status of the trace elements in Boju by using ICP-MS.Trace elements of the different parts of Boju and the soil near the roots were determined by microwave digestion-ICP-MS and the correlation of the data obtained was tested by using the statistical software.There were differences among the contents of the eight elements in the different parts of Boju and the soil; there were obvious differences in the enrichment factor of eight elements in the different parts of Boju, which ranged from 0.0054 to 0.9205; there was a significant positive correlation between Fe and Mg in the inflorescence and the contents of Fe was positively correlated with the soil; for Al, Ba and Mg, there were significant positive correlations between its soil contents and leaves contents.Boju absorbs the inorganic elements selectively,the yield and quality of Chinese medicinal materials can be improved by improving the cultivation.
