Objective: To determine the contents of five heavy metals in Radix Bupleuri medicinal materials from six main producing areas, and to provide more basis for quality control of Radix Bupleuri Radix. Methods: The experiment was conducted using the national standard under the “Food Hygiene Inspection Method” (GB/T5009-2003) for content determination; the “Green Industry Standard for the Import and Export of Medicinal Plants and Preparations” (2001) was used for evaluation. Results: The methodological investigation results are in line with the relevant requirements of the Ministry of Foreign Trade and Economic Cooperation; the content of heavy metals in Bupleurum chinense from different places is significantly lower than the national standard. Conclusion: The method is simple and reliable. The six major producing areas of Bupleurum chinense contain a certain amount of harmful heavy metals but the content does not exceed the standard.
