Front Cover: Rapid characterization of the constituents in Jigucao capsule using ultra high performance liquid chromatography with quadrupole time‐of‐flight mass spectrometry

DOI: 10.1002/jssc.202100664 The cover picture shows the qualitative analysis of Jigucao capsule (JGCC), a well-known Chinese Patent Medicine for the treatment of acute and chronic hepatitis and cholecystitis. A rapid and robust method was established by high-throughput ultra high performance liquid chromatography with quadrupole time of flight mass spectrometry. A total of 144 compounds in JGCC were characterized, which may be the active components of JGCC. For the first time, we report that many components of JGCC have been detected. It will provide a reference for the quality control of JGCC, as well as for the pharmacodynamic material basis research.
