Combination of high‐resolution accurate mass spectrometry and network pharmacology provides a new method for the chemical constituents’ study and target prediction in vivo of Garcinia multiflora

Abstract

Garcinia multiflora is a kind of evergreen tree which is widely distributed in the south of China. However, few researches focused on the constituents in different parts of G. multiflora as well as their potential targets and pathways in vivo. To clarify the chemical constituents of G. multiflora rapidly and predict the potential targets as well as pathways in vivo that this plant may have effects on, a feasible and accurate strategy was developed to identify the chemical constituents in fruits, leaves, and branches of G. multiflora by ultra‐high performance liquid chromatography with Q‐Exactive hybrid quadrupole‐orbitrap high‐resolution accurate mass spectrometry. Network pharmacology was then employed and a “compounds‐targets‐diseases” network was established. Sixty‐one compounds including polycyclic polyprenylated acylphloroglucinols, xanthones, and flavonoids were finally identified in different parts of G. multiflora, and the contents of seven constituents were quantified, respectively. On the basis of the network pharmacology analysis results, compounds in this plant were speculated to have potential pharmacodynamic effect on cancer, inflammatory, respiratory diseases, cardiovascular diseases, and metabolic diseases. This research will provide a new method for the advanced study on the pharmacodynamic materials basis of G. multiflora, and offer valuable evidences for medicinal purpose of this plant.

Metabolic profile and potential mechanisms of Wendan decoction on coronary heart disease by ultra‐high‐performance quadrupole time of flight‐mass spectrometry combined with network pharmacology analysis

“…In addition, network pharmacology can systematically monitor the effects of medications on illnesses based on the “disease‐gene‐target‐drug” connection, showing the characteristics of systems biology, network analysis, connectedness, redundancy, and pleiotropy. This approach is consistent with the assumption that TCM promotes a comprehensive approach to illness diagnosis and treatment [14–16]. To describe the bioactive components that account for WDD's therapeutic effects on CHD, network pharmacology could be used as a powerful tool to gain a comprehensive understanding of WDD's therapeutic mechanism and provide a link between its in vivo constituents and the corresponding biological targets.…”

Systematic characterization of the absorbed components of Ligustri Lucidi Fructus and their metabolic pathways in rat plasma by ultra‐high‐performance liquid chromatography‐Q‐Exactive Orbitrap tandem mass spectrometry combined with network pharmacology

“…Network pharmacology is a new method that combines system network analysis with pharmacology, which is different from the traditional method to study the complex interaction between components and targets of TCM. It can predict the interaction between components and gene protein diseases at the molecular level [23,24]. Furthermore, the components-targets-diseases whole model was established to explain the mechanism of action of drugs [25,26].…”
