Abstract: Objective:To establish the method of microbial limit test for Sanyu Zhitong Ointment,scientific methods and test results to ensure that the correct,reliable. Methods:Using Escherichia coli,Staphylococcus aureus,Bacillus subtilis,Candida albicans and Aspergillus niger strains and other five kinds of tests carried out recovery test bacteria,molds and yeasts,and bacteria control method validation check. Results:Using conventional methods,media dilution and centrifugation,five kinds of recovery test strains were less than 70%;Centrifugal- medium dilution method,five kinds of recovery test strains are up more than 70%;Control bacteria Staphylococcus aureus,Pseudomonas aeruginosa can be detected using the media dilution method(200 m L). Conclusion:Microbial limits Sanyu Zhitong Ointment,the bacteria,yeast and mold count must centrifugal- medium dilution method,Staphylococcus aureus and Pseudomonas aeruginosa check using medium dilution method.
