Abstract: According to the requirements of 1105, 1106 and 1107 in the fourth part of the Chinese Pharmacopoeia (2020),the applicability of the microbial counting method and control bacteria test for Yanhuanglian suppository was studied. The applicability research experiment in a sequential, scientific and reasonable way was carried out. The method of aerobic bacterial count was optimized by comparing the advantages of the sample solution dilution plate method and sample solution dilution membrane filtration method. The results showed that the total number of aerobic bacteria of Yanhuanglian suppository was determined by the method of dilution plate of sample solution (1∶200), the Staphylococcus aureus test was carried out by dilution method (1 000 mL), the Pseudomonas aeruginosa was detected by the routine method (100 mL TSB). The method adopted was in accordance with the relevant provisions of general principles of the fourth part of the Chinese Pharmacopoeia (2020),the reference method of preparation and applicability test of sample solution was provided for the suppository with bacteriostatic action and partial prescription components.

Key words: Yanhuanglian suppository, hospital preparation, suitability test, microbiological counting, Staphylococcus aureus
