| heal.abstract | A sensitive method was developed for the determination of biogenic amines at very low levels by combining solid phase extraction (SPE) and derivatization on-line with HPLC. The on-line derivatization and SPE were performed simultaneously on a commercially available ODS guard column, which was installed instead of the filling loop on the HPLC apparatus. Resolution of the peaks and quantification was further enhanced with micellar liquid chromatography and sensitization of the benzene ring absorption at 254 mn. Detection limits of the benzoyl derivatives of biogenic amines were in the vicinity of 0.1 mug L-1, which is even lower than those obtained by fluorescence detection and is unparallel to any other UV approach. The correlation coefficients of determinations were 0.9850-0.9998. The method was applied to the determination of Biogenic amines, that is, putrescine, cadaverine, agmatine, tyramine, tryptamine, phenylethylamine, spermine, spermidine and histamine in fish, chicken, and wine samples. Recovery of the proposed method ranged from 94 to 106%. | en |
