Abstract
Objective: To investigate six trace elements including Cr, Zn, Mn, Se, Cu and V of 13 traditional Chinese medicines (TCM) commonly used in diet therapy of diabetes mellitus. Method: The samples were prepared through digesting in a microwave oven and determined with Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Result: The correlative coefficients of the calibration curves were above 0. 999. Standard addition recovery was 88. 7% -110.0% and RSD ≤7. 0%. Under the given analytical conditions, the results obtained showed that the contents of the six trace elements varied in these TCM samples, for element Cr, ranging between 0-11. 82 μg · g-1, Mn in 4. 36-564. 3 μg · g-1, Cu in 0. 55-13. 34 μg · g-1, Zn in 3. 19-86. 23 μg · g-1 Se in 0-0. 39 μg · g-1 and V in 0. 05-12. 04 μg · g-1, respectively. Conclusion: The possible relationship between the content of the six trace elements and 13 TCM samples for dietetic therapy of diabetes mellitus was also discussed.
