摘要： 目的 建立高效液相色谱法拆分并测定盐酸索他洛尔对映异构体的含量。方法 采用CHIRALPAK AD-H手性固定相色谱柱（5 μm,250 mm×4.6 mm）,流动相为正己烷-乙醇（80︰20）,等度洗脱,检测波长为225 nm,流速为1.0 mL·min-1,柱温为25℃,进样量为10 μL。结果 盐酸索他洛尔2种对映异构体分离度良好,2个色谱峰之间的分离度大于2.0,2种对映异构体在1.005~100.5 μg·mL-1和1.073~107.3 μg·mL-1的浓度范围内线性关系良好（r=0.999）,平均回收率分别为97.05%[相对标准偏差（RSD）=2.26%]、98.24%（RSD=2.80%）。2种异构体的检测限均为0.1 μg·mL-1,定量限均为0.3 μg·mL-1,精密度试验、重复性试验与稳定性试验均良好。结论 所建立的方法准确可靠,灵敏度高,可用于盐酸索他洛尔对映异构体的拆分与含量测定。

Abstract: Objective To separate and determine the content of sotalol hydrochloride by HPLC. Methods A CHIRALPAK AD-H chiral phase column (5 μm, 250 mm×4.6 mm) was used, with a mobile phase of n-hexane-ethanol (80∶20), at the flow rate of 1.0 mL·min-1. The detection wavelength was 225 nm, the column temperature 25 ℃, and the injection volume was 10 μL. Results The two enantiomers were well separated, and the resolution between the peaks of the two enantiomers exceeded 2.0. The linearity between the two enantiomers was good within the range of 1.005~100.5 μg·mL-1 (r=0.999) and 1.073~107.3 μg·mL-1 (r=0.999), respectively. The average recovery of the two enantiomers was 97.05% and 98.24% respectively, with an RSD of 2.26% and 2.80%, respectively. The detection limit of the two enantiomers was 0.1 μg·mL-1, and the quantification limit was 0.3 μg·mL-1. The precision test, repeatability test, and stability test proceeded well. Conclusion The established method is accurate and reliable, which can be used in chiral separation and content determination of sotalol hydrochloride.
