  • Title: Comparison of different immunoaffinity clean-up procedures for high-performance liquid chromatographic analysis of ochratoxin A in wines.
    Author: Castellari M, Fabbri S, Fabiani A, Amati A, Galassi S.
    Journal: J Chromatogr A; 2000 Aug 04; 888(1-2):129-36. PubMed ID: 10949480.
    Abstract:
    Three immunoaffinity clean-up procedures to analyse ochratoxin A (OTA) in wines were compared. The direct wine clean-up with Ochraprep and OchraTest columns gave equivalent results in terms of recovery and precision if compared with the reference procedure involving a preliminary extraction of OTA with chloroform. OTA quantification limit in wine ranged from 0.020 to 0.045 microg/l. The 'on-flow' OTA emission spectrum (excitation 333 nm) showed a maximum at 460 nm and could be used to confirm the quantitative results. The analysis of 11 red and white wines gave no significant quantitative differences between the three clean-up techniques.
