To study the chromatographic behavior of cetirizine dihydrochloride on the proteinate- and amylose- based chiral stationary phases so as to optimizate the chromatographic condition of its enantiomers separation.
When using amylose-based, alpha1-acid glycoprotein and ovomucoid protein chiral stationary phase, the mobile phase was hexane-isopropyl alcohol-alcohol-trifluoroacetic acid (430:45:25:1), acetonitrile-10 mmol x L(-1) phosphate buffer solution (adjusted to pH 7.0 with sodium hydroxide) (4:96) and acetonitrile-20 mmol x L(-1) KH, PO4 solution (adjusted to pH 7.0 with triethylamine) (12.7:87.3), respectively. The temperature of proteinate column was 25 degrees C. The detective wavelength was 230 nm.
The two enantiomers could be separated on the two kinds of chiral stationary phases without derivatization and the resolution was above 2.0. The methods developed on the two kinds of chiral stationary phases are accurate, sensitive and specific.
Both the proteinate- and amylose-based chiral stationary phases can be used to separate the enantiomers of cetirizine.
研究盐酸西替利嗪在基于蛋白盐和直链淀粉的手性固定相上的色谱行为,以优化其对映体分离的色谱条件。
使用基于直链淀粉、α1-酸性糖蛋白和卵类粘蛋白的手性固定相时,流动相分别为正己烷-异丙醇-乙醇-三氟乙酸(430:45:25:1)、乙腈-10 mmol·L⁻¹磷酸盐缓冲溶液(用氢氧化钠调至pH 7.0)(4:96)和乙腈-20 mmol·L⁻¹KH₂PO₄溶液(用三乙胺调至pH 7.0)(12.7:87.3)。蛋白盐柱温度为25℃,检测波长为230 nm。
两种对映体在两种手性固定相上无需衍生化即可分离,分离度大于2.0。在两种手性固定相上建立的方法准确、灵敏且特异。
基于蛋白盐和直链淀粉的手性固定相均可用于分离西替利嗪对映体。
