Abstract:
OBJECTIVE To identify the chemical components of Changtong oral liquid （CTOL），and to provide reference for the basic research and secondary development of its pharmacological substances. METHODS UHPLC-Orbitrap HRMS technique was adopted. CTOL sample was separated on a Hypersil Gold column with mobile phase consisted of 0.1% formic acid （containing 5 mmol/L ammonium formate）-acetonitrile （gradient elution）. The eluent was detected in positive and negative ion modes using an electrospray ionization source. The data was processed by Xcalibur 4.3 and Compound Discoverer 3.3 software. The primary and secondary mass spectra data of each compound were collected. The unknown compounds were identified according to the mass spectrometry library of the instrument and the network databases mzCloud，mzVault，etc. Through matching with the pharmacology database and analysis platform of the traditional Chinese medicine system，the chemical components could be attributed to the traditional Chinese medicine. RESULTS Fifty-three chemical components were identified and analyzed from CTOL，such as 24 flavonoids，8 quinones，5 phenylpropanoids，4 sugars and glycosides，5 organic acids，3 amino acids，1 alkaloid，1 phenolic and 2 other compounds. Among them，12 components were derived from Salvia miltiorrhiza，9 from Citrus aurantium，7 from Rheum palmatum，4 from Angelica sinensis，1 from Magnolia officinalis，16 from Glycyrrhiza uralensis，and 4 from many kinds of medicinal materials. CONCLUSIONS CTOL mainly contains flavonoids，quinones and phenylpropanoid compounds，and its chemical components mainly come from G. uralensis，S. miltiorrhiza and C. aurantium.
