摘要
报道了全价饲料中喹乙醇的高效液相色谱分析方法。饲料样品用丙酮 -水溶液提取 ,在 Alltech-C185 μ(4.6× 2 5 0 mm)柱上进行分析 ,流动相为甲醇 -水 (2 5∶ 75 ,v/v) ,流速 0 .8m L/min,紫外检测波长 36 8nm,喹乙醇的平均回收率≥ 97.39% ,相对标准偏差 RSD≤ 1.78% (n=5 )
A HPLC method for the determination of olaquindox in the complete feeds was developed.The samples were extracted with 50 g/L K 2CO 3 acetone(1∶9).The HPLC system consists ALLTECH C18 5 μm column (4.6 mm i.d.×25 cm),the methanol water(25∶75,v/v ,0.8 mL/min) was used as mobile phase and the detection was carried out at 368 nm.The mean recovery is ≥9739% with RSD (n=5)≤1.78%.
