摘要
目的:建立以高效液相色谱法测定谷维素双维B片中维生素B6含量的方法。方法:以Ultimatec18柱(250mm×4.6mm,5μm)为色谱柱,甲醇O.075mol/L磷酸二氢钾溶液(13:87)为流动相,流速为1.0mL/min,检测波长为291nm。结果:维生素B6浓度在40-200μg/mL范围内与峰面积线性关系良好(r=0.9999,n=7),平均回收率为98.89%,RSD=0.60%(n=6)。结论:该方法简便、快速、准确可靠,可用于谷维素双维B片中维生素B6的含量测定。
Objective To establish a HPLC method for the determination of Vitamin B6 in Oryzaol. Vitamin B1 and Vitalmin B6 Tabietso Method Chromatographic condition included Ultimate C18 ( 250mm×4.6mm,5μm) column and mobile phase of mixture of methanol-0.075mol/L potassium dihydrogen phosphate ( 13: 87) o Flow rate was 1.0mL/min, the detection wavelength was 291nmo Result The standard curve of Vitalmin B6 was linear in the concentration from 40-200 μ g/mL (r=0.999 9, n=7) , the average recovery rate was 98.89%, RSD=0.60%(n=6). Conclusion This method is simple, rapid, accurate and can be used for the determination of Vitamin B6 in Oryzaol, Vitamin B1 and Vitalmin B6 Tablets
