ABSTRACT
<p><b>OBJECTIVE</b>To establish a comprehensive analytical high performance liquid chromatography fluorescence detection (HPLC-FL) in detecting bisphenol A (BPA), nonylphenol (NP) and octylphenol (OP) in canned food sold in Beijing markets.</p><p><b>METHODS</b>BPA, NP and OP was extracted with methanol and dichloroacetamide and concentrated. The samples were purified on an solid extraction cartridges. The HPLC system consisted of Waters XTerra MS C18 column, a mixture of methanol and water as mobile phase and fluorescence detector with the excitation and emission wavelength at 225 nm and 310 nm respectively.</p><p><b>RESULTS</b>The method established had a linear relationship, showing the detection limit of BPA, OP and NP being 0.5, 0.1 and 0.1 microg/kg in canned vegetable and instant noodle and 1, 0.5 and 0.5 microg/kg in canned fish and meat can, respectively. The recoveries of BPA, NP and OP were 74.9%-95.1% , 76.3%-103.6% and 72.1%-109.2%. The precision was 4.98%-11.2% , 2.35%-8.88% and 5.61%-12.3%, respectively.</p><p><b>CONCLUSION</b>The method is simple with high sensitivity and selectivity, suitable for the determination of NP, OP and BPA in canned food.</p>
