摘要：
A procedure for the simultaneous determination of the mycotoxins tenuazonic acid (TEA) and cyclopiazonic acid (CPA) is presented for the first time. It has been applied to tomato products and involves simple extraction, defatting and partitioning steps followed by metal complexation chromatography on a reverse phase C-18 column. The quantification limits in tomato products were 11.0 ng/g for TEA and 8.0 ng/g for CPA and the average recoveries were 88 and 78% for TEA and CPA, respectively. (C) 2000 Elsevier Science Ltd.
