摘要
Aim To establish a HPLC method for the separation of the enantiomers of zolmitriptan. Methods The separations were performed on Chiralcel OJ column with hexane-ethanol-diethylamine(85:15:0.2) as mobile phase at a flow rate of 0.8 mL·min^-1 and detecttion wavelength of 227 nm at 35 ℃. Several related parameters for separation were studied. Results Baseline separation (Rs 〉 1.5) was easily obtained in the case, and the R-isomer impurity in zolmitriptan was determined. Conclusion The method developed in this study has been successfully applied for quality-control purposes.
目的建立一种高效液相色谱法分离佐米曲普坦对映体。方法采用Chiralcel OJ色谱柱,以正己烷-乙醇-二乙胺(85∶15∶0.2)为流动相,检测波长227nm,流速0.8mL·min-1,柱温35℃,并对一些影响分离的参数进行了研究。结果佐米曲普坦对映体得到基线分离,并对佐米曲普坦样品中的R异构体杂质进行了检查。结论该方法已成功地应用于佐米曲普坦的质量控制。
