固相萃取-高效液相色谱法测定水产品中的甲基睾酮残留量
SPE-HPLC Determination of 17α-Methyltestosterone Residues in Aquatic Products
摘要
Abstract
A method to determine 17α-methyltestosterone (MET) residues in aquatic products was developed using LC-C18 solid phase extraction (SPE) combined with HPLC. Samples were extracted with diethyl ether under ultrasonic assistance. After concentration by rotary evaporation, the extract was defatted with n-hexane, cleaned up using an LC-C18 column, blown to dryness and dissolved again before reversed-phase HPLC analysis using a mobile phased made up of methanol and 0.1%formic acid (1:1, V/V ). The average recovery rates of the HPLC method for MET at spike concentrations of 7.0–200μg/kg were in the range of 82.0%–86.0%with a relative standard deviation (RSD) less than 7%. The limit of quantification (LOQ) for MET was 7.0μg/kg.关键词
