Isoeugenol residues in Australasian snapper (Pagrus auratus) white muscle, blood plasma and seawater were accurately and precisely quantified after extraction with acetonitrile using fluorometric detection (ex. 260 nm, em. 340 nm) without chromatographic separation. Isoeugenol residues in Australasian snapper (P. auratus) muscle tissue following 30 min exposure to 58.2 mu mol L-1 isoeugenol (ca. 20 ppm of the aquatic anaesthetic AQUI-S (TM)) reached a maximum of 134.37 +/- 8.13 mu mol kg(-1) (+/- SEM; n = 6). Blood plasma isoeugenol concentrations following this harvesting regime were 253.2 +/- 25.1 mu mol L-1. After 7 h recovery, fillet isoeugenol residues reduced to 7.89 +/- 1.67 mu mol kg(-1). Storage of fillets from fish harvested with AQUI-S (TM) at 3.87 +/- 0.54 degrees C for 5 days resulted in a rate of isoeugenol decay in the fillets of 6.51 +/- 1.19 mu mol kg(-1) day(-1). The method reported can be used for measuring isoeugenol residues in food products or to further study the physiological and biological effects of isoeugenol in fish. (C) 2012 Elsevier Ltd.
