摘要
目的建立维他参颗粒中维生素B1含量测定方法,为维他参颗粒质量标准的研究提供科学依据。方法采用高效液相色谱法测定维他参颗粒中维生素B1的含量。色谱条件为Agilent XDB-C18(5μm 150 mm×4.6 mm)色谱柱,以乙腈-0.008 mol/L己烷磺酸钠-三乙胺-冰醋酸(12∶87∶0.25∶0.75)为流动相;检测波长为246 nm。结果此方法线性良好,平均加样回收率为99.8%,RSD为2.0%。结论本方法精密度高,分离度良好,可用于测定维他参颗粒中维生素B1的含量。
Objective To establish the method for determining the content of Vitamin B1 in Weitashen Granules. Method Determining the content of Vitamin B1 by HPLC, chromatographic condition XDB-C18 5μm 150mm × 4. 6 mm column, the mobile phase was Acetonitrile -0. 008mol/L sodium 1-hexanesulfonate-thiethyl- amineglacid-acetic acid ( 12 : 87 : 0. 25 : 0. 75 ) , detection wavelength at 246nm. Results The average recovery was99. 8% , relared standard devfation (RSD) was 2. 0% . Conclution This method can be used to determine the content of Vitamin B1 in Weitashen Granules.
