Quality Control and Adulteration Detection of Cattle Bile Powder Based on Bile Acids / 中国药学杂志

ABSTRACT

OBJECTIVE: To establish a method for the quality control of cattle bile powder based on cholic acid components, evaluate the quality of commercially sold cattle bile powder, and analyze the possible adulteration. METHODS: A method was established for simultaneous determination of cholic acid content in bile powder of cattle, sheep, pig, chicken, duck and other animals. Self-made samples and samples collected by enterprises were studied respectively. Based on self-made samples, the differences and content rules of bile powder of cattle, pig, sheep and other animals were investigated, and the quality and possible adulteration of samples collected by enterprises were evaluated. RESULTS: An HPLC-ELSD method was established for simultaneous determination of 12 cholic acids in bile powder of cattle, sheep, pigs, chickens and ducks. By analyzing the determination results of 23 batches of self-made animal bile powder, the contents of cholic acid in cattle bile powder and other animal bile powder were determined. By analyzing the determination results of cattle bile powder samples collected from 23 enterprises, it was found that there were mainly two kinds of adulteration of cattle bile powder likely: sheep bile powder and cholic acid waste. Only 8 of the 23 batches of samples collected by enterprises met the requirements, and the qualified rate was only 34.8%. The quality of varieties needs to be improved and supervised urgently. CONCLUSION: The method established in this study can effectively control the quality of cattle bile powder, identify possible adulteration of cattle bile powder, and provide reference and basis for improving the quality standard of cattle bile powder and strengthening market supervision.
