ABSTRACT
To evaluate the pesticide residue risk of Jinyinhua Formula Granules( made from Lonicerae Japonicae Flos) used in the market preliminarily,20 samples of Jinyinhua Formula Granules from 5 manufactures were collected randomly through the national evaluative sampling test program. Totally 262 pesticides( involving 270 chemical monomers) with monitoring significance to traditional Chinese medicinal materials were detected. Samples were extracted by high speed homogenate with acetonitrile as solvent. And their residues were analyzed by GC-MS/MS and LC-MS/MS in MRM mode. No less than 2 groups of characteristic ion pairs were adopted for qualitative detection,and the calibration curve method was used for quantitative detection. The results showed that 20 pesticides were detected in 20 batches of Jinyinhua Formula Granules,with an average of about 9 pesticides detected in every batch,but no restricted pesticide was detected. The detected pesticides were all at the trace level,which was far lower than the limit of the general food standard. Therefore,the safety risk was low in Jinyinhua Formula Granules. In this study,a screening method for pesticide residues in Jinyinhua Formula Granules was established for the first time. The method was accurate and rapid,and the detection indicators were highly targeted. The results could provide theoretical reference for the prevention and control of pesticide safety risks in Jinyinhua Formula Granules and even traditional Chinese medicine formula granules.
