Abstract

OBJECTIVE To establish an analytical method for the determination of 14 kinds of organophosphate pesticide residues in Flos Lonicerae Japonicae by solid-phase extraction(SPE) and Gas Chromatograph-mass spectrometry.METHODS Ultrasonication with acetone in ice bath was used for sample preparation.The sample was processed by SPE column added with 0.2 g active carbon.The total ion current(TIC)was identified with a spectrum library search.Selected ion monitoring(SIM)was used as quantify.RESULTS All the organophosphate pesticide showed good linearity in a detected concentration range with good correlation coefficient(r=0.980 2~1.000 0).The method recoveries were generally 65.02%~107.04% with RSD 3.6%~8.0% and the limit of detection was 0.017 9~0.092 5 ppm(S/N =3).CONCLUSION The method is effective,fast,accurate and provide an analytical method of the organophosphate pesticide residue in traditional medicine.
