Abstract:
Objective:To investigate the microbial contamination status of Chinese herbal pieces from Guangxi regions and provide reference for the microbial limit standard. Methods:According to Chinese Pharmacopoeia (2015 edition), the herbal pieces were analyzed for the total number of aerobe microbial, yeasts, molds, thermophilic bacteria and bile-resistant gram-negative bacteria,and salmonella was also detected. Results:In 90 batches of Chinese herbal pieces,the lg average value of the total number of aerobe microbial was 3.7,and that of the total yeasts and molds was 1.7,that of thermophilic bacteria was 0.9 and that of bile-resistant gram-negative bacteria was 1.1,and Salmonella was not detected out. There were statistically significant differences (P < 0.05) in the microbial contamination levels of herbal pieces with different processing techniques and packaging materials. Conclusion:According to different processing methods and administration, microbial limit standard should be established for classification in order to guide the standardized production of Chinese herbal pieces and improve their quality gradually.
