An analytical method based on high-performance liquid chromatography (HPLC) combined with fluorescence detection (FL) has been developed for the simultaneous determination of fumonisin B1 (FB1) and its totally hydrolized metabolite aminopentol-1 (AP1) in pig liver. The sample preparation is based on a single solid phase extraction (SPE). o-Phthalaldehyde (OPA) was used for precolumn derivatization before the programmed reversed-phase analysis on phenylhexyl column. The developed method shows good repeatibility for inter- and intra-day precision as well as adequate linearity of calibration curves (r2 was 0.9855 for FB1 and 0.9831 for AP1). Average recoveries from the matrix were 93.6 % for FB1 and 95.3 % for AP1. The limit of quantification (LOQ) in swine liver was 75 µg/Kg for FB1 and 42 µg/Kg for AP1.

Abstract
An analytical method based on high-performance liquid chromatography (HPLC) combined with fluorescence detection (FL) has been developed for the simultaneous determination of fumonisin B1 (FB1) and its totally hydrolized metabolite aminopentol-1 (AP1) in pig liver. The sample preparation is based on a single solid phase extraction (SPE). o-Phthalaldehyde (OPA) was used for precolumn derivatization before the programmed reversed-phase analysis on phenylhexyl column. The developed method shows good repeatibility for inter- and intra-day precision as well as adequate linearity of calibration curves (r2 was 0.9855 for FB1 and 0.9831 for AP1). Average recoveries from the matrix were 93.6 % for FB1 and 95.3 % for AP1. The limit of quantification (LOQ) in swine liver was 75 µg/Kg for FB1 and 42 µg/Kg for AP1.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
