Quantitative Determination of 16 Elements in Zhenzhu Mingmu Eye Drops
Objective: To investigate the effects of pharmaceutical technology and the quality of raw material on trace elements contents in Zhenzhu Mingmu eye drops
and provide information for the quality control and quality safety of this preparation. Method: The contents of Pb
Cd
As
Hg
Cu
Mg
Al
K
Ca
Cr
Mn
Zn
Sr
Pd
Ba
W in 102 batches of Zhenzhu Mingmu eye drops from 7 manufacturers were determined by inductively coupled plasma mass spectrometry (ICP-MS) method. Result: Various elements showed good linear relationship (r>0.999)
and the recovery rate was within 78.6%-97.6%
RSD within 2.5%-9.5%
indicating the quantitative method was accurate and reliable. Conclusion: The results showed that the contents of As and Hg in some samples exceeded the recommended limits; the content of trace elements in products of few enterprises were quite different among the samples from other manufacturers
and the obvious fluctuation was even existed for the products from the same manufacturer.
