[Abstract]
Objective To investigate the chemical composition of Shensong Yangxin Capsule, a novel ultra high performance liquid chromatography-quadrupole/orbitrap high resolution mass spectrometry (UHPLC-Q-Orbitrap HRMS) was employed to establish a method that could identify the ingredients systematically and rapidly. Methods The information of accurate mass and multistage fragment ions was obtained by the novel UHPLC-Q-Orbitrap technology. Chemical constituents were characterized by comparing the relative retention time and the mass data of the reference substance, meanwhile consulting the reference literature or the Mass Bank, Chemical Book network database. Results A total of 54 compounds were finally identified in this research, including the phenolic acids, flavones, terpenoids, anthraquinones, alkaloids and others. Conclusion A method was established in this study to identify various chemical constituents of Shensong Yangxin Capsule systematically, rapidly and accurately. The identified chemical components mostly cover the main constituents of each medicinal material in the formula. Our work will lay a scientific foundation for the bioactive components screening, quality control improvement and further clinical application of this herbal formulation.
