Identification and fingerprint of Qinsu Capsule based on high resolution mass spectrometer
Objective,2,To qualitatively analyze the chemical composition of Qinsu Capsule (QSC) by Ultra performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry (UPLC-Q-TOF/MS) and mass spectrometry database, and establish HPLC fingerprint for QSC.,Methods,2,The Agilent ZORBAX RRHD SB-C,18,(2.1 mm×100 mm, 1.8 μm) was used with a mobile phase of acetonitrile-0.1% methanoic acid in gradient elution. The flow rate was 0.3 mL/min, the column temperature 25 ℃, and the detection wavelength 270 nm. UPLC-Q-TOF/MS was used for qualitative analysis in the positive and negative ion modes. The chromatographic fingerprints analysis of 10 batches of QSC were carried out in the Waters Xbridge Shield RP,18,(4.6 mm×250 mm, 5 μm) column with a mobile phase of acetonitrile-0.05% phosphoric acid in gradient elution, the flow rate 0.8 mL/min, the column temperature 30 ℃, and the detection wavelength 270 nm.,Results,2,Totally 68 chemical components were detected from QSC, and 22 of them were identified. The HPLC fingerprint for 10 batches of QSC was established and 33 common peaks were obtained. The similarity of 10 batches of QSC was over 0.990.,Conclusion,2,The chemical composition of QSC was qualitatively analyzed and HPLC fingerprint was established, which can provide support for the further study of substance basis and quality standard promotion of QSC.
