目的:建立喉疾灵胶囊的微生物限度检查法。方法:采用常规平皿法、培养基稀释法,通过测定喉疾灵胶囊对5种试验菌株的回收率,对喉疾灵胶囊微生物限度检查法的有效性进行评价。对必检控制菌的检查法进行验证。结果:采用常规平皿法,试验菌的回收率不能全部达到70%以上;采用培养基稀释法,试验菌的回收率高于70%;控制菌可采用常规法。结论:该方法简单、快捷,可用于喉疾灵胶囊的质量控制。
Objective: To establish a microbiological limit test for Liaoxianling Capsule. METHODS: The effectiveness of the method of microbiological limit test of GZK was evaluated by measuring the recoveries of five kinds of test strains by conventional plate method and medium dilution method. Verification of the inspection method of the control bacteria must be verified. Results: The use of conventional plate method, the recovery rate of the test bacteria can not reach more than 70%; using the culture dilution method, the recovery rate of the test bacteria is higher than 70%; control bacteria can be used routinely. Conclusion: This method is simple and rapid and can be used for the quality control of GZL.
