Objective:To determine the content of total mercury in Zizhu Ointment, and to provide evidence for its effectiveness and safety. MethodsAfter microwave digestion of samples, the content of total mercury was determined by inductively coupled plasma optic emission spectrometry (ICP-OES). Results:In the established method for determining total mercury, the linearity was Y=4 587X-150.1 and the correlation coefficient was 0.999 9. The recovery rate was 89.29%~101.36% and the average content of total mercury in Zizhu Ointment was 3.20%, with RSD of 1.28%. Conclusion:ICP-OES is a rapid, accurate and reliable method for the determination of total mercury in Zizhu Ointment.
