Abstract:In this paper, fluorescein isothiocyanate (FITC) as a pre-column derivatization reagent, the derivatives of biogenic amines in soy-based, high-performance liquid chromatography (HPLC) with laser-induced fluorescence detector (LIFD) in conjunction with technology, the product of the derivative were tested. Established derivatives of biogenic amines in soy sauce and separation, this study investigated the derivative temperature, buffer pH, reaction time and other factors derived fi'om biological amine derivative of the impact study of the mobile phase, flow rate,temperature and other conditions on the separation effect. Derivative conditions: derived temperature 50℃, buffer pH 8-10, derivative time 12 h, separation conditions: mobile phase: acetonitrile - water, flow rate: 1.0mL/min, at room temperature.
Keywords:biogenic amines  derivatization  FITC  HPLC- LIFD
