Simultaneous Determination of Six Saponins in Xinyue Capsules by UPLC-MS/MS
Objective:To establish the method for determination of ginsenoside Rg1,ginsenoside Re,ginsenoside Rb1,pseudo-ginsenoside F11,ginsenoside Rd and 20(S)-ginsenoside F1 in Xinyue Capsules by ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS).Methods:The analysis was performed on Waters ACQUITY BEH C18 column(100 mm×2.1 mm,1.7 μm),with acetonitrile(A)-water(B)as the mobile phase,with gradient elution at a flow rate of 0.5 mL·min-1.The column temperature was set at 40℃.The analytes were detected using the electrospray ionization(ESI)source in multiple reaction monitoring(MRM)scan mode.Results:Six constituents showed good linear relationships within the concentration ranges of 9.638-963.800,9.839-983.900,9.951-995.100,5.270-1 054.000,9.608-960.800,4.905-981.000 ng·mL-1(r>0.998),whose average recoveries(RSD)were 96.9%(2.2%),100.1%(1.5%),97.2%(1.8%),98.5%(2.3%),96.6%(2.8%),100.2%(3.5%),respectively.Conclusion:The established method is rapid,accurate,and highly sensitive,making which can be used for quality control of total ginsenosides from Panax quinquefolium stems and leaves in Xinyue Capsules.
