Analysis of the microbial contamination status of trichosanthis fructus decoction pieces / 中国药学杂志

ABSTRACT

OBJECTIVE: To investigate the microbial contamination of trichosanthis fructus decoction pieces, and provide a reference for the test method and standard of the microbial limit. METHODS: Trichosanthis fructus decoction pieces were tested for the total aerobe microbial count, the total combined yeasts and molds count, the thermoduric bacteria count, the bile-tolerant gram-negative bacteria, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella. RESULTS: The total contamination percentages of aerobes, combined yeasts and molds, thermoduric bacteria, bile-tolerant gram-negative bacteria of trichosanthis fructus are 100%, 59%, 91%, and 91%, respectively. Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and salmonella of trichosanthis fructus were not detected. CONCLUSION: To assure the safety of trichosanthis fructus decoction pieces, it is recommended to control the total aerobe microbial count, the total combined yeasts and molds count, the thermoduric bacteria count, the bile-tolerant gram-negative bacteria, escherichia coli, staphylococcus aureus, pseudomonas aeruginosa and salmonella.
