  • Title: [Determination of Diphenylamine in Agricultural Products by HPLC-FL].
    Author: Aoyagi M, Chiba M, Kakimoto Y, Nemoto S.
    Journal: Shokuhin Eiseigaku Zasshi; 2016; 57(6):201-206. PubMed ID: 28025454.
    Abstract:
    A method for the determination of diphenylamine in agricultural products was developed. Diphenylamine was extracted with acetonitrile from a sample under an acidic condition, passed through a C18 cartridge column, re-extracted with n-hexane, cleaned up on a PSA cartridge column, determined by HPLC with fluorescence detector and confirmed by liquid chromatography with tandem mass spectrometry. Average recoveries (n=5) from brown rice, corn, soybeans, potato, cabbage, eggplant, spinach, orange, apple and green tea were in the range from 76.7 to 94.9%, and the relative standard deviations were from 0.6 to 5.8% at concentrations equal to the maximum residue limits (MRLs). The quantification limits were 0.01 mg/kg, which is the uniform limit in the positive list system for agricultural chemical residues in food in Japan.
