Abstract:

A method for the determination and quantification of tau-fluvalinate, triadimenol and coumaphos in royal jelly was
established by HPLC-MS-MS. Tau-fluvalinate, triadimenol and coumaphos residues were extracted by acetonitrile under alkaline
condition, and clean-up of the extracts was carried out using HLB solid phase extraction (SPE) column. Quantification was conducted by
HPLC-MS-MS coupled with multiple reaction-monitoring (MRM) system using electron spray ionization source in an external standard
mode. The detection limits for coumaphos, triadimenol and tau-fluvalinate residues were 2, 1 μg/kg and 1 μg/kg, respectively. The
recovery rates of tau-fluvalinate, triadimenol and coumaphos residues at three spiked levels (5, 10 μg/kg and 50 μg/kg) in different samples
were in the range of 78.9%–102.1% with relative standard deviation of 2.1%–13.6%. The linear range of detection was 5–100 μg/kg (r >
0.9940). This method can be successfully applied to the qualitative and quantitative analysis of royal jelly samples.
