Objective: There are rich in mineral elements in Tibetan medicine Renqing Mangjue
in which contain a lot of Hg
Pb and As besides the human body essential trace elements and macro elements. So to establish the method for determination 24 inorganic elements in Renqing Mangjue by micrwave digestion-inductively coupled plasma mass spectrometry (ICP-MS). Method: A method was studied for the assay of many inorganic elements such as Cr
Mn
Ni
Co
Cu
Zn and As in Renqing Mangjue by microwave digestion-inductively coupled plasma mass spectrometry with Rh and Re as internal standards. Result: Detection limits for above elements were 0.003 2-2.419 g·g-1
with the recoveries were 80.62%-108.2% except for Hg. Conclusion: Established a fast
accurate and reliable method for assay of 24 inorganic elements in Renqing Mangjue. Which are foundations for the further research the species of every element in Renqing Mangjue
its pharmacological effects and establish the quality standard of Renqing Mangjue.
