摘要
采用薄层扫描法测定猪肝中克伦特罗残留量,用GF254板作载体,乙酸乙酯-甲醇-醋酸(8:l:0.8)为展开剂,克伦特罗的Rf值为0.8l。线性范围0.004～0.050μg,回收率为86.5%～94.9%,RSD为5.0%～5.8%(n=6)。
The analytical method of Clenbterol (CL) residue in swine liver by thin-layer chromatography scanningdetermination was developed.With EtOAc-MeOH-HOAc(8:1:0.8)as mobile phase and on the silica gel GF plate, the Rf valueof CL was 0.8l.The calibration curve was linear in the range of 0.004～0.050μg.The average recovery was 86.5%～94.9% andthe RSD of CL was 5.0%～5.8%(n=6).
