Abstract:

A method for the simultaneous determination of 2-methoxyphenol, 2-methoxy-4-methylphenol, 2,6-dimethoxyphenol and 4'-hydroxy-3'-methoxyacetophenone in urine has been described. The metabolites were analyzed after enzymatic hydrolysis and extraction on octyl (C8) cartridges by using gas chromatography with flame ionization detection and a 5/95% copolymer of diphenyl-poly(dimethylsiloxane) capillary column. Methoxyphenols were well separated within 12 min. Recovery was over 90% in the range from 0.5 to 20 microg/ml; the detection limit was varying in the range of 0.05-0.11 microg/ml. The relative standard deviations and the accuracy were in the range of 3.1-15.5 and 2.4-16.0%, respectively.
