摘要
采用手性色谱柱(Chiralcel OD-RH 150×4.0 mm,5μm),以0.05 mol/L的KPF6缓冲液(用磷酸调节pH值为3.0)-乙腈(体积比50∶50)为流动相,在流速1.0 mL.min-1、检测波长280 nm条件下分离和测定了苯磺酸顺阿曲库铵的R-S和S-S异构体.结果表明,利用高效液相色谱法可以实现苯磺酸顺阿曲库铵的R-S和S-S异构体的手性拆分及其快速、简便、准确测定.
A chiral column （Chiralcel OD-RH 150×4.0mm,5μm） was used to separate and determine the R-S isomer and S-S isomer of cisatracurium besilate at a flow rate of 1.0 mL·min^-1 and detection wavelength of 280 nm, in the presence of 0.05 mol/L KPF6 buffer solution （The pH value was adjusted to 3.0 with phosphoric acid solution） plus acetonitrile （volume ratio 50：50） as the mobile phase. Results indicate that the R-S isomer and S-S isomer of cisatracurium besilate can be efficiently separated by high performance liquid chromatography （HPLC）. And the HPLC method can also be used to determine the two types of isomers rapidly, simply, and accurately.
