Abstract
As a compound preparation of traditional Chinese medicine, Jianwei Xiaoshi Tablets (JXT) is made from five Chinese herbs: Taizishen (Pseudostellariae Radix), Chenpi (Citri Reticulatae Pericarpium), Shanyao (Dioscoreae Rhizoma), Maiya (Hordei Fructus Germinatus) and Shanzha (Crataegi Fructus). It is mainly used to treat dyspepsia. However, the chemical composition of JXT is complex and unclear. In this study, ultra performance liquid chromatography-quadrupole-orbitrap-mass spectrometry and data post-processing technologies were used to analyse the samples of JXT. Firstly, the mass spectrometric information of the main components of five traditional Chinese herbs in JXT was summarised and a compound database was established. Then, the mass spectrometric data detected by the prepared samples was compared with the database. Finally, 93 chemical components were successfully identified, including 6 amino acids, 34 flavonoids, 18 alkaloids, 15 organic acids, 9 cyclic peptides and 11 other components, and the rapid classification and identification of chemical components of JXT were realised.
