摘要 建立了替米考星的高效液相分析方法 .在流动相为水 乙腈 四氢呋喃 磷酸丁胺缓冲液 (体积比为 80 5∶110∶6 0∶2 5 ) ,流速为 1 0mL/min ,色谱柱为ODS柱 (4 6mm× 2 0 0mm ,5 μm)的条件下 ,其保留时间为 6 5min和7 5min(顺式 +反式 ) ,可实现快速分离 .检测波长为 2 80nm时 ,在 2 0~ 8 0 μg的范围内 ,样品量与峰面积呈现良好的线性关系 ,最低检测限为 1 7μg ,方法的回收率在 99%~ 10 1% ,相对标准偏差 (RSD)小于0 5 % .该方法简便、快速 ,稳定性好 。 The analytical method of Timicosin by high performance liquid chromatography(HPLC) is developed with the mobile phase of water,cetonitrile,THF and phosphoric acid-butylamine,the flow-rate of 1mL/min,the column of ODS(4.6 mm×200 mm,5 μm) and the detection wavelength of 280 nm.Under the optimal condition,the retention time of Timicosin is 6.5 min and 7.5 min(maleinoid form and transform),the low detection limit is 1.7 μg.This method is simple,rapid and of good stability,which can be used to determine the batch samples.
