Abstract: Objective: To develop a microbial limit test method for Coptis chinensis. Methods: Establish the method suitability test and sample inspection method according to“microbial limit test methods for Chinese Herbal Medicine”(exposure draft) of Chinese Pharmacopoeia. Results: Microbiological counting method suitability test: dilute Coptis chinensis by 1∶20, then continue the microbial recovery test referring to plate pouring method. Control bacteria examination method suitability test: dilute Coptis chinensis by 1∶20, take specified quantity of testing liquid to test Escherichia coli and Salmonella paratyphi according to different test methods. Conclusion: Confirmed by method suitability test, the method can be used for microbial limit test for Coptis chinensis.

Key words: Coptis chinensis, Microbial limit test, Method suitability, Total number of aerobic bacteria, Total number of molds and yeasts, Control bacteria examination
