Abstract

A method has been developed for confirmatory determination of chrysoidine in fish by GC–MS. Samples were extracted with methanol, and an aliquot was subjected to dispersive solid-phase extraction clean-up with octadecyl sorbent. After centrifuging and filtering, extracts were evaporated to dryness and derivatized with acetic anhydride. The detection and quantification limits were 2.3 and 7.7 μg kg−1 respectively, demonstrating the potential of the method for quality control of food.
