Abstract

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.
