Investigation and Analysis of Pesticide Residues in Fructus Trichosanthis / 中国药学杂志

ABSTRACT

OBJECTIVE: To investigate the status of pesticide residues in Fructus Trichosanthis. METHODS: Seventy kinds of pesticide residues were detected by GC-MS-MS and 150 kinds of pesticide residues were detected by HPLC-MS-MS in 84 samples of Fructus Trichosanthis from leading producers of 11 provinces. RESULTS: The detection rate of pesticide residues in 84 Fructus Trichosanthis samples was 95.2%, with only 4 batch of samples without pesticide residues detection. Endosulfan sulfate, diphenlamine, fenvalerate, chlorantraniliprole, carbendazim, cyhalothrin, and bifenthrin had the highest detection rates, all above 10%. CONCLUSION: The detection rate of pesticide residues in Fructus Trichosanthis is high, but most of the detected pesticides have low contents, with few samples exceeding the limits.
