摘要：

A reversed-phase high-performance liquid chromatographic method was developed for the simultaneous determination of the usually co-eluting peaks of ochratoxin A and zearalenone by fluorescence detection due to specific inclusion phenomena using beta-cyclodextrin as a mobile phase additive. Additionally four different clean-up techniques were studied in order to optimize the recoveries of ochratoxin A and zearalenone in the range 0.5-1000 ppb (w/w) in maize, including liquid-solid extraction using Florisil, C18 and plain silica solid-phase extraction mini-columns and a base-acid liquid-liquid partitioning clean-up procedure.
