Objective: To establish a quantitative method for the free amino acids in Ziziphi Spinosae Semen. Method: Acquity UPLC BEH Amide column(2.1 mm×100 mm
1.7 μm)was used for chromatographic separation
temperature of the column was set at 35℃. The flow rate was 0.4 mL·min-1. Waters XevoTM TQ worked in multiple reaction monitoring mode(MRM). Result: In 12 min
the investigated compounds were determined without derivatization. Our method was validated in terms of sensitivity
recovery
linearity as well as repeatability. Conclusion: The established method can be helpful for evaluation the quality control of Ziziphi Spinosae Semen.
