Rapid Analysis of Chemical Components of Zhitong Huazheng Capsules Based on UPLC-Q-TOF/MS Technology Combined with UNIFI Database / 中国药房

ABSTRACT

OBJECTIVE： To rapidly identify chemical components of Zhitong huazheng capsules （shorted for “ZTHZC”）， and to provide reference for further elucidating the pharmacodynamic material basis and overall quality control. METHODS： UPLC-Q-TOF/MS method was adopted to separate the chemical components of ZTHZC. By reviewing literatures that related to chemical components of ZTHZC and its single Chinese traditional medicinal crops， the chemical structure of the chemical components was saved into a .mol format file， and supplemented the UNIFI database. The chemical constituents of ZTHZC were qualitatively analyzed by UNIFI database screening， and validated according to their precise molecular mass， characteristic ions， neutral loss， secondary mass spectrometry cleavage， chromatographic retention behavior， combined reference information and literature reports. RESULTS： A total of 70 chemical components were identified in this experiment， including 38 organic acids and organic acid esters， 8 alkaloids， 9 flavonoids， 5 triterpenoid saponins， 5 aldehydes， 2 ketones， 1 quinone， 1 polyacetylene and 1 monoterpenoid. CONCLUSIONS： This study provides a rapid detection and identification method for chemical components of ZTHZC， and also provides a scientific basis for the clarification of ZTHZC’s quality control and pharmacodynamics.
