ABSTRACT
Objective:
To identify the major chemical constituents in Cortex Juglandis Mandshuricae by ultra performance liquid chromatography coupled with time-of-flight mass spectrometry (UPLC-Q-TOF/MS).Methods:
The separation was performed on Waters Acquity UPLC BEH C18 column (100 mm×2.1 mm, 1.7 μm), with a mobile phase using water with 0.1% formic acid (A) and acetonitrile with 0.1% formic acid (B) for gradient elution; Q-TOF/MS and electrospray ion (ESI) source was applied for the analysis under the positive and negative ion modes; Target search and non-target search were performed by Peakview 2.0/masterview1.0 or Markerview 1.2.1 software. Then the formulas of compounds were determined by accurate mass and isotopic abundance ratio from target screening function of software. Their structures were determined by analysis of MS/MS fragment or comparison with standard substances and references.Results:
Forty-four major chemical compounds including 13 naphthalene quinones, 3 diarylheptanoids, 15 flavonoids, and 13 other compounds were identified or inferred in Cortex Juglandis Mandshuricae.Conclusion:
UPLC-Q-TOF/MS method which develops a new strategy can identify the main chemical constituents from Cortex Juglandis Mandshuricae rapidly and accurately, main chemical constituents can be used for quality evaluation and pharmacological research.
