瓜蒌药材农药残留情况的调查与分析

Investigation and Analysis of Pesticide Residues in Fructus Trichosanthis

目的了解瓜蒌药材的农药残留情况。方法从瓜蒌主产地的11个省份中收集84批样品,采用气相色谱-质谱联用法对70种和液相色谱-质谱联用法对150种农药进行检测。结果 84批样品中农药检出率为95.2%,仅4批样品中无农药残留检出,其中硫丹硫酸盐、二苯胺、氰戊菊酯、氯虫酰胺、多菌灵、氯氟氰菊酯的检出率超过10%。结论瓜蒌药材中农药检出率较高,但大部分检出值较低,仅部分批次样品残留超限,但是部分国家禁限用农药存在超限问题,应该引起相关部门的重视。

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 Fruetus Trichosanthis from leading producers of 11 provinces. RESULTS The detection rate of pesticide residues in 84 Fructus Tri- chosanthis 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%. CONCLU- SION The detection rate of pesticide residues in Fruetus Trichosanthis is high, but most of the detected pesticides have low contents, with few samples exceeding the limits.
