Abstract:
The excessive pesticide residues and heavy metals in traditional Chinese medicine seriously endanger human health and the sustainable development of Chinese medicine industry. In order to improve the quality of traditional Chinese medicine and establish a general standard for maximum residue limits(MRL) of pesticides in pollution-free traditional Chinese medicine and decoction pieces, and to ensure the safety of clinical medication from its origin, MRLs were calculated based on the formula(MRL=A×W/100M) from Chinese Pharmacopeia, comparing it with the current Chinese and international standards as well as literature review, the RAND/UCLA appropriateness method(RAM) was applied to determine the categories and MRLs of pesticides in pollution-free traditional Chinese medicine and decoction pieces. Two questionnaires were drafted for expert panel and appropriateness analysis was carried out with the 9-point Likert scale to determine the general standard for MRLs of pollution-free traditional Chinese medicine and decoction pieces. The results showed that a total of nine experts from different fields scored the necessity of standard-setting and 206 pesticide residue limits respectively. The appropriateness scores of 206 pesticides were greater than 7, and appropriateness rate was 100%, which signifies that the expert panel has reached consensus. In summary, based on the RAM, the general standard for maximum residue limits of pesticides in pollution-free Chinese medicines and decoction pieces has reached an expert consensus. Comparing with the MRLs of medicinal plants and plant-sourced food from CAC, Europe Union, the United States, South Korea, Japan, Australia, New Zealand and Canada, 206 MRLs from this general standard share 88.8% in common, 4.4% of which is higher and 6.8% lower than those international standards. This has provided a basis for standardizing the use of pesticides in pollution-free traditional Chinese medicine.
