Abstract
The present study aimed to investigate the intervention mechanisms of Rhizoma Coptidis using spontaneously hypertensive rats. A serum metabolomics analysis was performed with high performance liquid chromatography‑quadrupole/time of flight mass spectrometer in positive mode. The obtained data were further analyzed by principal component and partial least‑squares discriminant analysis to reveal differentiating metabolites. The pattern of metabolites in the serum after Rhizoma Coptidis exhibited distinct alterations. A total of 10 potential biomarkers were significantly altered in the serum and may be associated with the underlying mechanism. Alterations were primarily associated with phospholipid metabolism, fatty acid metabolism, amino acid metabolism and arachidonic acid metabolism. In addition, biochemical alterations in potential biomarkers were associated with inflammation, nitric oxide production, platelet aggregation and endothelial function. By analyzing and verifying the specific biomarkers, metabolomics may be helpful to further understand the underlying therapeutic mechanism of Rhizoma Coptidis. Metabolomics is a powerful tool used to investigate the therapeutic effects of herbal medicine with multiple targets.
