英文摘要:

A rapid method to identify and quantify unconjugated progestogens in eggs is presented. Samples were prepared based on matrix solid-phase dispersion (MSPD) using C18 as dispersant, followed by a cleanup step with graphitized carbon black (GCB) solid-phase extraction (SPE) cartridges. The analytes were separated by very high pressure LC on a BEH C18 column for a period of 5 min, Electrospray ionization tandem mass spectrometry (ESI-MS/MS) was operated in the positive time-scheduled multi-reaction monitoring mode. Recovery studies were performed at two fortification levels. Average recoveries of the target compounds varied from 83.8% to 111.2% and relative standard deviations ranged from 10.5% to 23.7%. The limits of detection (LODs) and limits of quantitation (LOQs) were in the range of 0.2-2.0 mu g kg(-1) and 0.6-5.0 mu g kg(-1), respectively. Investigation of real samples indicated that the range of progesterone in eggs was 9.9-40.0 mu g kg(-1). (C) 2008 Elsevier B.V. All rights reserved.
