Reversed-phase high-performance liquid chromatographic analytical system for aflatoxins in wines with fluorescence detection


, : Reversed-phase high-performance liquid chromatographic analytical system for aflatoxins in wines with fluorescence detection. Journal of Chromatography 131: 147-156

An improved procedure using reversed-phase high-performance liquid chromatography (HPLC) with fluorescence detection is described for the analysis of 6 aflatoxins (B1, B2, G1, G2, B2a and G2a). The method provides greater analytical speed, reproducibility and resolution, and better accuracy and sensitivity than the previously available TLC methods. Aflatoxins B1 and G1 were hydrated to enhance their fluorescence response. Analyses of hydrated and unhydrated compounds by HPLC provided simultaneous qualitative and quantitative information. A typical HPLC run was complete in 15 min. The recoveries of 4 aflatoxins (B1, B2, G1 and G2) from wines at the spiked level of 1 .mu.g/l (1 ppb) were satisfactory. The method as applied to wine samples is sensitive at the 0.02 .mu.g/l level.
