Pesticide residue is a major exogenous pollutant of traditional Chinese medicine (TCM)

which seriously affects the safety and efficacy of TCM

therefore

it is necessary to systematically investigate the pesticide residue and establish data files of TCM. According to the test results of pesticide residues from 11 kinds of TCM samples collected from the fourth Chinese Materia Medicine Resource Survey in 2012-2014

and 2016. In the analysis results of a total of 542 batches of TCM samples

pesticide residues were detected in 263 batches

of which only 5 batches had exceeded content of the pesticide residues accounting for about 0.92% of the total TCM samples

and the pesticide residues content of the remaining TCM samples was less. In the statistics analysis of pesticide residues from different species

different medicinal parts and different producing areas

there were some common low-toxic pesticides and also some high-toxic pesticides which have been banned for using in some TCM samples. This phenomena shall be received great concern by the relevant departments. This paper would put forward some reasonable recommendations and some pesticide varieties which need to be monitored according to the analysis results

with a view to providing some effective data

establishing monitoring and management systems and perfecting the standard on pesticide residues of TCM samples for "Chinese Pharmacopoeia".
