Abstract: 目的 建立元胡止痛系列制剂统一的指纹图谱.方法 采用Thermo Acclsim 120 C18(4.6 mm×250 mm,5 μm)色谱柱,乙腈-甲醇(4∶1)为流动相A,25 mmol· L-1乙酸钠溶液(含庚烷磺酸钠15 mmol·L-1,用冰醋酸调pH =6.4)为流动相B,检测波长:280 nm;柱温:35℃,流速:1 mL· min-1进行梯度洗脱.结果 指纹图谱共标定9个共有峰,利用对照品比对归属了5个峰,另采用Waters xevo G2 Q-Tof LC/MS对另外4个色谱峰进行了指认.结论 该方法分析时间短、耐用性好,可用于元胡止痛系列制剂的质量控制.
