摘要: 建立超高效液相色谱串联质谱法同时测定赤芍药材中的没食子酸、氧化芍药苷、芍药内酯苷、芍药苷、苯甲酰芍药苷含量的分析方法。采用Acquity UPLC BEH C18柱(2.1 mm×50 mm,1.7 μm);流动相为0.1 %甲酸乙腈溶液(A)-0.1 %甲酸水溶液(B),梯度洗脱,电喷雾离子源(ESI),选择性离子监测(SIR)模式进行正负离子同步监测。没食子酸、氧化芍药苷、芍药内酯苷、芍药苷和苯甲酰芍药苷在0.134~31.250、0.014~2.784、0.471~30.750、0.293~75.040和0.158~40.360 μg/mL浓度范围线性关系良好,平均加样回收率为91.36%~112.83%,RSD为1.1%~8.9%。该方法准确、高效、重现性好、专属性高,可用于赤芍药材的质量控制。

Abstract: To establish a UPLC-MS method for simultaneous determination of gallic acid,oxypaeoniflorin,albiflorin,paeoniflorin and benzoylpaeoniflorin in Radix Paeoniae Rubra. An Acquity UPLC BEH C18 column (2.1 mm×50 mm,1.7 μm) was used for the chromatographic separation with the mobile phase consisting of 0.1% formic acid in acetonitrile (A) and 0.1% formic acid in water (B) by gradient elution.Selected ion recording (SIR) mode was used for detection.The linear ranges of gallic acid,oxypaeoniflorin,albiflorin,paeoniflorin and benzoylpaeoniflorin were determined to be 0.134~31.250,0.014~2.784,0.471~30.750,0.293~75.040 and 0.158~40.360 μg/mL,respectively.The average recoveries were 91.36%~112.83%,with RSDs of 1.1%~8.9%.The developed UPLC-MS method was accurate and effective.It can be used for the quality evaluation of Radix Paeoniae Rubra with simultaneous determination of 5 marker compounds.
