摘要: 建立了阿折地平对映体的高效液相色谱拆分方法。采用Chiralpak AD-H (250 mm×4.6 mm, 5.0 μm, Daicel公司)手性色谱柱在正相条件下直接拆分阿折地平对映体,考察了固定相种类、流动相组成及柱温等对阿折地平对映体分离的影响。确定了最佳的拆分条件: 流动相为正己烷-异丙醇(90:10, v/v),流速为0.8 mL/min,检测波长为254 nm;柱温为20 ℃;在此条件下阿折地平对映体的分离度为3.3。该法简单快速,重现性好。

Abstract: A high performance liquid chromatographic (HPLC) method was established for the enantiomeric separation of azelnidipine. Baseline chiral separation of azelnidipine was achieved under normal-phase chromatographic mode using the Chiralpak AD-H chiral column (250 mm×4.6 mm, 5.0 μm, Daicel). The influences of the nature of chiral stationary phase, form of the mobile phase, and column temperature on the enantiomeric separation were studied. The optimized chromatographic conditions were hexane-isopropyl alcohol (90:10, v/v) as the mobile phase with a flow rate of 0.8 mL/min and detection at the wavelength of 254 nm. The column temperature was set at 20 ℃. The resolution of 3.3 for azelnidipine was achieved under the above chromatographic conditions. The method is simple, rapid and with good reproducibility.
