Abstract: 建立了高效液相色谱法分离肾上腺素、去甲肾上腺素、异丙肾上腺素的苄氧羰基衍生物对映体的方法.以氯甲酸苄酯为衍生化试剂,在室温、碱性条件下,对3种肾上腺素类药物进行衍生化反应.采用手性CHIRALPAKAD-RH色谱柱,在检测波长为226 nm条件下,考察了流动相、流速、柱温对对映体手性分离的影响.结果表明,肾上腺素、去甲肾上腺素、异丙肾上腺素衍生物对映体分别在乙醇为流动相、流速为0.5 mL/min、柱温为25 ℃;甲醇-乙醇(体积比3:1)为流动相、流速为1.0 mL/min、柱温为25 ℃;甲醇-水-四氢呋喃(体积比150:20:7)为流动相、流速为0.5 mL/min、柱温为25 ℃时,分离效果最佳.
