摘要
采用外标法测定维生素K2(20)的含量,建立了维生素K2(20)的RP-HPLC测定方法.色谱柱为AgilentZORBAX Eclipse XDB-C18(150mm×Φ4.6mm,5μm),流动相为甲醇,检测波长为270nm,流速为1.0mL·min^-1,线性范围为0.04~0.4mg·mL^-1(r=0.9996).方法操作简便,重现性好,可用于维生素K2(20)的含量测定.
A HPLC external standard method for the determination of menatetrenone was established. The column : Agilent ZORBAX Eclipse XDB- C18 (150 mm ×Φ4.6 mm, 5μm), mobile phase:methanol, flow rate:1.0 mL·min^- 1, detection wavelength : 270 nm. Calibrated linear curve of menatetrenone concentratrion was in the range of 0.04--0.4 mg· mL^- 1 ( r = 0. 999 6). This reliable and reproducible HPLC analysis offers an option in the quality control of menatetrenone.
