Abstract: Objective To determine the contents of pearl powder in ZhupoQingnao tablets. Method EDTA volumetric method was used to determine the contents of CaCO3 in tablets which was used to control pearl powder contents indirectly. Results The method was accurate with recovery of CaCO3 being (98.60+0.58)%; the method was reproducible with RSD being 1.02%;the pearl powder contents(indicated by contents of CaCO3) in five different lots tablet samples were 14.63 mg, 14.52 mg, 14.59mg , 14.62 mg and 14.55 mg respectively. Conclusion EDTA volumetic method is accurate, sensitive ,reproducible and it can be used to determine pearl powder contents in ZhupoQingnao tablets.
