摘要

目的:探索适用于甘草饮片的微生物限度检查方法。方法:依据《中华人民共和国药典》2025年版(四部)通则1108的要求,采用常规法、增加稀释液法和直接接种法,对3家不同企业生产的甘草饮片进行微生物限度检查方法的适用性试验。结果:采用常规法进行需氧菌总数和耐热菌总数测定时,金黄色葡萄球菌和枯草芽孢杆菌的回收未达到规定要求(0.5~2.0)。供试液稀释50倍后,枯草芽孢杆菌回收合格;稀释100倍后,金黄色葡萄球菌的抑制作用被有效消除,所有试验菌的回收试验均符合要求。霉菌和酵母菌总数测定采用常规法,各菌回收率均达标。控制菌检查中,方法适用性试验及阳性对照试验均检出目标菌,阴性对照无菌生长,符合规定。结论:本研究建立的微生物限度检查法简便、可靠,可用于甘草饮片的日常质量控制,也为复方甘草片等中成药的微生物限度检查提供方法参考。

Abstract

Objective: To explore the microbial limit test methods applicable to licorice decoction pieces. Methods: According to the requirements of Chinese Pharmacopoeia (2025 edition,Part Ⅳ)general rules 1108, the conventional method,Incremental Dilution method and direct inoculation method were adopted for applicability test of the microbial limit test method for Licorice decoction pieces from three manufacturers. Results: When the conventional method was used for total aerobic microbial count and total thermophilic microbial count, the recovery rate of Pseudomonas aeruginosa and Staphylococcus aureus failed to meet the requirements(0.5~2.0). After a 50-fold dilution of the test solution, the recovery of Pseudomonas aeruginosa met the requirements. Following a 100-fold dilution, the inhibitory effect on Staphylococcus aureus was effectively eliminated, and the recovery rates of all test strains met the requirements. The conventional method was employed for the determination of total combined yeasts and molds counts, and the recovery rates of all strains were within the required range. In the tests for controlled microorganisms, both the method suitability test and positive control test successfully detected the target strains, with no growth was observed in the negative control, conforming to the pharmacopoeial requirements. Conclusion: The microbial limit test methods of Licorice decoction pieces established in this research is simple and reliable, and can be used for the routine quality control of Licorice decoction pieces.It also provides a methodological reference for the microbial limit inspection of Chinese patent medicines such as Compound Glycyrrhiza Tablets.
