Integrating UPLC-QE-Orbitrap-MS technology and network pharmacological method to reveal the mechanism of Bailemian capsule to relieve insomnia

Abstract

Bailemian capsule (BLMC) is a Chinese patent drug for treating insomnia with excellent curative effects. But there are few researches on it. In this research, a rapid separation and identification method using UPLC-QE-Orbitrap-MS was established, and 228 identified compounds were separated within 18 min. The structures of compounds were preliminarily determined by comparing the retention time and fragmentation law. Furthermore, multiple databases were used to integrate the compound targets of BLMC and the disease targets related to insomnia. After the intersection of the two sets of targets, a protein-protein interaction network and a drug-target-disease pharmacological network were established, then using the DAVID database to perform GO analysis and KEGG analysis on the common targets to find related pathways. Finally, a total of 289 common targets and 136 pathways were found to participate in the mechanism.
