Abstract: This study analyzed the pesticide residue and heavy metal contents in Panaxnotoginseng (Burk.) F.H.Chen to provide the basis for the quality criterion of pollution-freemedicinal materials and slices of notoginseng.We randomly collected 100 samples of notoginseng from farmer's markets,producing areas of notoginseng and internet markets.We entrusted the third-party authoritative testing institutions to detect 203 items of the pesticide residues and 4 items of heavy metals.According to relative standards of Japan,Korea,the United States and the European Union,we analyzed and summarized the data in this study.We confirmed the 25 species of pesticides with high operating frequency and detection rate and the limited amount index of 4 heavy metals.In conclusion,these results enriched the limited amount index of the pesticide residues and heavy metal contents based on the previous notoginseng standard system serving as the quality criterion of pollution-free notoginseng,which was applicative and operable.
