本文报道用简便、快速的液相层析(LC)法测定多元组分制剂中醋氨酚.在此方法中,选用十八烷基硅烷(ODS)为色谱柱,柱长300×4.6mm(id);甲醇-醋酸(1:3)为流动相;在254nm或280nm处进行检测.该方法回收率为98.9±0.7%,方法的总
This article reports the simple and rapid liquid chromatography (LC) method for the determination of acetaminophen in multicomponent formulations. In this method, octadecylsilane (ODS) was used as the column with a column length of 300 × 4.6 mm id); methanol-acetic acid (1: 3) as mobile phase and detection at 254nm or 280nm.The recoveries of this method were 98.9 ± 0.7%
