摘    要:目的:建立测定左亚叶酸钙原料药中右旋异构体含量的高效液相色谱方法。方法:采用CHIRAL-HSA色谱柱(150mm×4.0mm,5μm),流动相为0.1mol·L-1磷酸二氢钠缓冲液(用氢氧化钠溶液调节pH至5.0)-异丙醇-乙腈(890∶95∶15);流速为1.0mL·min-1;检测波长为286nm;柱温为40℃。结果:在1.5~10.0μg·mL-1范围内线性回归方程为Y=29.125X-1.0025(r=1.0000),平均回收率为100.1%(RSD=0.8%,n=9)。结论:该方法操作简便、灵敏度高、重复性好。

Abstract:Objietive:To establish a HPLC method for determination the content of dextroisomer in Calcium levofolinate.Methods:The separation was performed on a human albumin coated silica gel column (150mm×4.0mm,5μm).The mobile phase was 0.1mol·L-1 sodium dihydrogen Phosphate buffer(adjust to pH 5.0 with sodium hydroxide solution)-2-propanol-acetonitrile(890:95:15).The flow rate was 1.0 mL·min-1 .Ultraviolet absorption detector was set at 286 nm and column temperature was at 40℃.Results:The linear range of dextroisomer was between 1.5 and 10.0 μg·mL-1 (r=1.0000).The average recovery was 100.1 % with RSD was 0.8%.Conclusions:A reproducible and specific method is provided for the content of dextroisomer in Calcium levofolinate .
Keywords:HPLC  Calcium levofolinate  Dextroisomer
