摘要
鳗鱼肉中己烯雌酚用甲醇超声萃取,浓缩蒸干,再用甲醇溶解,经0.45μm滤膜过滤,滤液在280 nm检测波长处用紫外检测器高效液相色谱仪检测。结果表明:鳗鱼肉中己烯雌酚平均回收率可达到84%以上,相对偏差小于15%,最低检测限为10μg/kg。
To establish a high sensitive method for determination of diethylstilbestrol residues in eel by high performance liquid chromatography（HPLC）, diethylstilbestrol in samples was extracted with methyl alcohol after dehydration with anhydrous sodium sulfate, then determined by HPLC with a UV detector at a wavelength of 280 nm. The results showed the lowest limit of detection was 10μg/kg,the recovery rates of detected samples were over 84%.
