目的 建立一种对中药制剂精制冠心软胶囊中复杂化学成分快速、高效的鉴定分析方法，为系统研究其化学组成提供基础数据。方法 应用超高效液相色谱-四级杆/静电场轨道阱高分辨质谱（UHPLC-Q-Orbitrap HRMS）技术对精制冠心软胶囊中的化学成分进行鉴定分析。通过多级离子碎片信息与对照品比对，结合文献数据进行准确定性。结果 共鉴定出精制冠心软胶囊中43种化学成分，主要包括黄酮类、苯酞类、有机酸类、醌类及其他等。结论 本方法可系统、准确、高效鉴定精制冠心软胶囊中化学组成，为其物质基础和质量控制研究提供科学理论依据。

Objective In order to establish a rapid and efficient analysis method for identification of the complex components in Jingzhi Guanxin Soft Capsule, and provide the basic research data for the systematic elaboration of its chemical constituents. Methods An ultra-high performance liquid chromatography-quadrupole/Orbitrap high resolution mass spectrometry (UHPLC-Q-Orbitrap HRMS) was used for the identification analysis of the components in Jingzhi Guanxin Soft Capsule, and the multistage fragments ions data was compared with the standard substance and literature consulting. Results Forty-three compounds were identified in this study, including flavones, phthalides, organic acids, quinones and other categories. Conclusion The chemical constituents of Jingzhi Guanxin Soft Capsule are identified systematically, accurately and efficiently, which provide the theory basis for the further research of its pharmacodynamic material basis and quality control.
