Abstract: 目的 建立以高效液相色谱法测定复方盐酸普鲁卡因溶液III中盐酸普鲁卡因含量的方法.方法 采用高效液相色谱法,用Ultimate LP-C18色谱柱(4.6 mm×250 mm,5 μm),以0.1%庚烷磺酸钠的0.05 mol·L-1磷酸二氢钾溶液(用磷酸调pH至3.0)-甲醇(68∶ 32)为流动相,流速为1.0 mL·min-1,检测波长为290 nm.结果 盐酸普鲁卡因线性范围为10.66~106.6 μg·mL-1(r=0.999 7),平均加样回收率为99.2%(RSD=0.8%).结论 该方法快速、方便,操作简单,其他成分无干扰,适用于测定复方盐酸普鲁卡因溶液III中盐酸普鲁卡因的含量.
