Kurzfassung:
Our previous studies confirmed the efficacy of gross saponins of Tribulus terrestris L. fruit in treating cerebral ischemia. This study aimed to investigate the related mechanisms in vitro. The lipopolysaccharide‐induced BV2 cells model was constructed and treated with gross saponins at different concentrations to explore its anti‐inflammatory activity. The cell metabolite changes were tracked by liquid chromatography‐mass spectrometry (LC‐MS)‐based metabolomics, and the metabolic biomarkers and related metabolic pathways were analyzed. Molecular biochemistry analysis was further used to verify the relevant inflammatory pathways. The results showed that the saponins reduced nitric oxide release and the secretion of tumor necrosis factor‐alpha, interleukin‐1β, and interleukin‐6 from lipopolysaccharide‐induced BV2 cells. Metabolic perturbations occurred in lipopolysaccharide‐treated BV2 cells, which could be reversed by drug treatment via mainly regulating glycerophospholipid metabolism, tryptophan metabolism, purine metabolism pathways, etc. The western blot analysis demonstrated that saponin could suppress the activation of the inflammatory‐related signaling pathway. The present study explored the in vitro anti‐inflammatory mechanism of gross saponins of Tribulus terrestris L. fruit using an LC‐MS‐based cell metabolomics approach, which confirms the great potential of LC‐MS for drug efficacy evaluation and can be applied in other herbal medicine‐related analyses.
