Chemical composition identification and mechanism study of Tenghuang Jiangu Capsule based on UHPLC-Q-Orbitrap HRMS and network pharmacology / 中草药

ABSTRACT

Objective: To systematically study the chemical components of Tenghuang Jiangu Capsule, explore the main mechanism of action, and provide some evidences for the research of its pharmacodynamic substances. Methods: In this study, UHPLC-Q-Orbitrap HRMS was used to comprehensively analyze the main chemical components of Tenghuang Jiangu Capsule. According to the MS/MS spectrometry information of compounds, the chemical information of this herbal formula can be quickly and accurately identified by comparison with standards or references. Next, the BAT-MAN-TCM database was used to predict the targets of the identified chemical components. The KEGG pathway annotation analysis and GO enrichment analysis were further carried out through the DAVID database to screen out the main pharmacodynamic substances of Tenghuang Jiangu Capsule and explore the potential mechanisms. Results: A total of 34 chemical components were identified in Tenghuang Jiangu Capsule. The "component-target" network analysis indicated that the major components including kaempferol, isoflavoues aglycone, ursolic acid, formononetin, and stigmasterol might act on some key targets such as Bcl-2, BAX, AKt, PPARG, PTGS1, PTGS2, TNF, IL6, F7, IL1B, etc. The results indicated that osteoclast differentiation, NF-κB, PI3K-Akt, renal cell, and platelet activation might be the main action pathways of exerting the therapeutic effect of bone protection, nourishing kidney, promoting blood circulation and relieving pain of Tenghuang Jiangu Capsule. Conclusion: In this study, UHPLC-Q-Orbitrap HRMS combined with network pharmacology was used to preliminarily clarify the chemical composition and reveal potential mechanism of Tenghuang Jiangu Capsule. The results provided scientific theoretical basis for screening the effective ingredients and further clarifying the mechanism of action of Tenghuang Jiangu Capsule.
