目的:采用双层膜过滤方法,建立具有抗菌活性的中药固体制剂微生物限度检查微生物计数方法。方法:设计新型微生物检查用双层膜过滤器,以30~50μm作为预过滤膜,0.22μm作为终端滤膜,采用《中国药典》微生物计数适用性试验方法,进行验证试验,考察预过滤对供试液中微生物的影响情况。结果:双层膜过滤方法,可以有效避免颗粒物堵塞滤膜,利于消除供试液抗菌活性,降低实验过程对样品中微生物造成的损伤或损失。结论:双层膜过滤法实验过程符合《中国药典》相关规定,试验结果有效,可用于药品的无菌检查或微生物限度检查试验。
目的:採用雙層膜過濾方法,建立具有抗菌活性的中藥固體製劑微生物限度檢查微生物計數方法。方法:設計新型微生物檢查用雙層膜過濾器,以30~50μm作為預過濾膜,0.22μm作為終耑濾膜,採用《中國藥典》微生物計數適用性試驗方法,進行驗證試驗,攷察預過濾對供試液中微生物的影響情況。結果:雙層膜過濾方法,可以有效避免顆粒物堵塞濾膜,利于消除供試液抗菌活性,降低實驗過程對樣品中微生物造成的損傷或損失。結論:雙層膜過濾法實驗過程符閤《中國藥典》相關規定,試驗結果有效,可用于藥品的無菌檢查或微生物限度檢查試驗。

Objectives:To develop a new method of two-membrane filtration in microbial enumeration tests for solid preparation of traditional Chinese medicine.Methods:New iflters with double thin membranes were designed by using different pore-size membranes: pre-iflter membrane with 30 μm-50 μm, and terminal iflter membrane with 0.22 μm t. The effects of pre-ifltration of test solution on several strains were evaluated by the methods described in Chinese Pharmacopoeia.Results:The established method of two-membrane ifltration can eliminate the antibacterial activity of the samples, thus reducing the injury or loss of microorganisms in special samples.Conclusion: The two-membrane ifltration method meets the requirements of Chinese Pharmacopoeia;the test results are valid and the method can be used for sterility test and microbial limit test for drug substances.
