  • Title: Biogenic amine determination in wines using solid-phase extraction: a comparative study.
    Author: Peña-Gallego A, Hernández-Orte P, Cacho J, Ferreira V.
    Journal: J Chromatogr A; 2009 Apr 10; 1216(15):3398-401. PubMed ID: 19232626.
    Abstract:
    Biogenic amines in wine usually are analyzed by high-performance liquid chromatography after direct derivatization. A method of isolation based on solid-phase extraction (SPE) with mixed-mode resins (Oasis MCX, reverse-phase and ion exchange) was developed. The different stages of the isolation process (loading, elution and washing) were optimized to obtain a simple procedure that yields a clean chromatogram. The relative standard deviation (%RSD) of the retention times and relative areas was less than 0.3% and 6%, respectively. Limits of quantification were lower than 0.16 mg L(-1) for all the amines and the linear range of concentration was 0.16-8 mg L(-1) for putrescine, cadaverine and tyramine, and up to 10 mg L(-1) for histamine.
