[Measurement of zinc in Mongolia patent drug Zhuangxiyin Powder with pulse stripping voltammetry].
OBJECTIVE
To determine the content of zinc in Mongolia patent drug Zhuangxiyin Powder.


METHODS
Differential pulse stripping voltammetry was employed for measurement of zinc.


RESULTS
The zinc content in three samples of the drug was (493+/-11.95)microg/g, (526+/-13.74)microg/g and (554+/-9.84) microg/g respectively, and the relative standard deviation (RSD) was 2.42%, 2.61% and 1.78% respectively.


CONCLUSIONS
The content of zinc in Zhuangxiyin Powder of daily dosage is higher than the needed daily intake of healthy people.
