Abstract:Objective To develop an ultra-performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometric (UPLC-Q/TOF-MS) method to analyze the chemical constituents in the drug pair of "Cinnamomum cassia Presl and Paeoniae Radix Alba". Methods Agilent 1290 UPLC machine and YMC-Triart C18 column (100 mm × 2.1 mm, 1.9 μm) were adopted to separate ingredients; the mobile phase was acetonitrile (A)-0.1% acetic acid solution (B) with gradient elution; the column temperature was 30℃; the inject volume was 5 μL; the detection wavelength was set at 254 nm; the flow rate was 0.3 mL/min; the mass spectrometer AB 5600 with an electrospray ionization (ESI) interface was under positive or negative mode for data collection. Results 8 compounds were identified by reference substance, 13 compounds were qualitative identified according to the MS/MS information, and the belonging of the main constituents had been confirmed. These compounds included six kinds of organic acid such as gallic acid and protocatechuic acid, tentotal paeoniflorin monoterpenes like paeoniflorin and albiflorin, and coumarins. Conclusion Determination of chemical composition of "Cinnamomum cassia Presl and Paeoniae Radix Alba" by UPLC-Q/TOF-MS in order to clarify the "Cinnamomum cassia Presl and Paeoniae Radix Alba" drug on the basis of the material to provide strong evidence.
