- W2808332854 abstract "目的利用UPLC-Q-Exactive四极杆-静电场轨道阱高分辨质谱仪联用技术，快速识别与鉴定民族药小大黄Rheum pumilum的化学成分。 方法以100%甲醇作为提取液制备供试液，采用ACQUITY UPLC BEH C18色谱柱（100 mm×2.1 mm，1.7μm）分离，以甲醇-0.1%甲酸水溶液为流动相进行梯度洗脱，质谱采用正负离子监测模式、采用全扫描及自动触发二级质谱扫描的功能，对小大黄化学成分进行快速识别及鉴定。 结果通过高分辨数据共鉴定了34个化学成分，包括蒽醌类11个，酚/酰基糖苷类4个、鞣质前体及鞣质类3个、二苯乙烯类9个、黄酮类2个、萘苷类3个、苯丁酮类2个，其中7个成分经与对照品比对而准确鉴定，28个化学成分为该植物中首次报道。 结论使用UPLC-Q-Exactive四级杆-静电场轨道阱高分辨质谱技术，建立高分辨质谱数据库，总结对照品裂解规律，使用少量对照品快速分析鉴定出多个小大黄化学成分，有利于明确小大黄的物质基础，表明该技术在中草药化学成分分析及鉴定方面具有良好的应用前景。" @default.
