Abstract: Objective To study the current mycotoxin contamination in traditional Chinese medicine, analyze the error sources and control methods of mycotoxin detection, and provide reference for reliable detection of mycotoxin in traditional Chinese medicine. Methods Theoretical research and literature review were used to summarize the sources of errors in the detection of mycotoxin, a traditional Chinese medicine. Recommendations were offered about the methods of error control. Results Sampling, as the first step of mycotoxin detection, was directly related to the accuracy of detection results, but was the biggest source of errors. Sample preparation was directly correlated with results of analysis and served as an important guarantee of the accuracy of test results. In order to ensure the accuracy of results of mycotoxin detection, a well-designed sampling scheme, appropriate sample preparation methods and sensitive and accurate analysis techniques should be used. Conclusion This paper has explored the sources of errors and control methods of mycotoxin detection in terms of sampling, sample preparation, analysis and detection so as to provide reference for improving the quality of analysis and reducing the analysis risk of mycotoxin detection in traditional Chinese medicine.
