Objective: To provide a theoretical guide for the production and application of Herba Asari.
Method: A GC method for multiresidue analysis was used.
Result: Fifteen samples of Herba Asari were detected with the method for the first time. The contents of organochlorine pesticide residues in most of the samples were under the Chinese national limits for grains and green vegetables (GB 2707-2763-81). The other samples were polluted seriously.
Conclusion: Some suggestions have been put forward to help keep down pesticide residue pollution in Chinese herbal medicines.
