UPLC—Q—TOF—MS/MS快速分析苁蓉总苷胶囊化学成分(1)
[摘要] 该文采用超高效液相色谱-四极杆飞行时间高分辨率质谱(UPLC-Q-TOF-MS/MS)技术对苁蓉总苷胶囊中化学成分进行了定性分析。液相条件:Agilent SB-C18Rapid Resolution HD (3.0 mm×100 mm,1.8 μm) 色谱柱,以乙腈-0.1%甲酸水溶液为流动相进行梯度洗脱,体积流量0.2 mL·min-1,柱温30 ℃,检测波长330 nm;质谱条件:采用ESI源,负离子模式下进行数据采集。通过与对照品对比、数据库匹配分析及参考文献资料,共推测出苁蓉总苷胶囊中的41个化合物。该方法能快速检测苁蓉总苷胶囊的化学成分,为苁蓉总苷胶囊的质量控制提供参考,也为其药效物质基础的进一步研究奠定基础。
