SPE-HPLC法检测食品中多种痕量雌激素
Determination of Trace Estrogens in Food by SPE-HPLC
摘要
Abstract
The residues of Ethinylestradiol,Diethylstilbestrol,4-Nonylphenol and Estradiol ben-zoate in food were determined simultaneously by SPE-HPLC. The samples were ultrasonic extract-ed with acetonitrile,centrifuged,concentrated and purified by C18 solid phase extraction column,an-alyzed with the HPLC method. This study optimized the conditions of SPE,and four components were well separated. The detection limit of the method was ranged from 6 to 12μg/kg. The recovery rates were 80. 3%~107. 8%. The calibration curves were linear with correlation coefficient ranged from 0.998 8 to 0.999 8. The relative standard deviations were 0. 124%~1. 72%. This method has high sensitivity,fine separability,simple sample preparation,and can reduce the inteference of im-purities,which is satisfied with the estrogen analysis.关键词
