Fast and versatile multiresidue method for the analysis of botanical insecticides on fruits and vegetables by HPLC/DAD/MS.

A simple multiresidue method for screening analysis of 12 botanical insecticides used by organic farmers has been developed. The method involves a rapid and small-scale extraction procedure with acetonitrile. For all fruit and vegetable samples, there was no need for clean up. Rotenone, azadirachtin, ryanodines, and pyrethrins can be separated by high-performance liquid chromatography, quantified, and confirmed with a diode array detector (DAD) and atmospheric pressure chemical ionization mass spectrometry (APCI-MS) in the select ion-monitoring mode (SIM). The majority of pesticide recoveries for various fruits and vegetables were >70% in the concentration range from 0.01 to 5 mg/kg. The limit of quantitation for most of the pesticides was 0.01 mg/kg, with the majority of relative standard deviations (RSD) mostly below 10%.[1]
